Abstract. The informatization of the international society is becoming a historical
trend, and the smart campus is gradually developing. But at present, there are
widespread problems in the campus, such as the lack of systematic management of
idle items and lost items, poor information of learning information, scattered port
of releasing information and low efficiency of dissemination. The team proposed
to design the campus mutual aid small program “Garden” platform, gathering lost
and found, idle goods trading, postgraduate entrance examination information,
campus notification services. And the small program function development needs
analysis, hoping to provide more efficient and convenient campus service platform
for students. Effectively solve the practical problems existing in school life and
realize the network and information of campus mutual aid.

1 Introduction
The background of today’s times is that several development trends in the information
age have become irreversible historical trends and are changing the face and pattern
of today’s world. [1] In 2010, in the 12th Five-Year Plan for informatization, Zhejiang
University proposed to build a “smart campus”. [2] On June 7, 2018, the national standard
“Overall Framework of Smart Campus” was released [3]; The National Conference on
Education Work in 2022 clearly proposed the implementation of the strategic action
on digitization of education. [4] Promoting intelligent campus life can provide more
convenient services for teachers and students. Therefore, our team conducted research
and analysis on the visible needs of life in the field of smart campus, hoping to make a
smart campus small program “Garden”.
At present, the environmental and resource problems brought by economic develop-
ment are increasingly serious. The 14th Five-Year Circular Economy Development Plan
issued by the National Development and Reform Commission in July 2021 proposed to
standardize and develop the second-hand commodity market [5]. The team conducted

Research and Development and Promotion of Campus 429
relevant investigation and research on second-hand commodity trading in the univer-
sity, and found that there was indeed great potential for development, and decided to
add a second-hand transaction page in “Garden”. Since The State Council issued Sev-
eral Opinions on Accelerating the Development of the Service Industry in March 2008,
China has developed rapidly in the service industry [6]. In the development of the ser-
vice industry, the lost and found system can improve the basic equipment of the service
industry and improve the quality of the service industry, which is an indispensable link.
However, in the campus environment with a high incidence of lost goods, there is a lack
of intelligent lost and found management system construction. So our team decided to
add the smart campus lost and found system in “Garden”; According to the website of
the Ministry of Education, the scale of postgraduate education has seen a breakthrough
in the past decade, and the demand for postgraduate entrance examination continues
to grow. As far as studying for postgraduate entrance examination is concerned, it is
difficult to break the poor information and find reliable information efficiently. Just like
the small program “Ai scholar” can easily find journals and conferences, the information
platform of “Garden” can also easily find learning information.
To sum up, the team designed the WeChat mini program “Garden” platform, which
will focus on providing students with quick and practical service functions such as lost
and found, idle goods transaction, campus notice and postgraduate entrance examination
information. The team hopes to apply the computer knowledge on campus to respond
to the national call and better meet the needs of students.
2 The Significance of Relevant Research
(1) Lost and Found
The large flow of campus people is the high incidence of relics. At present, the
information of our school’s relics collection is only spread through WeChat moments
and QQ Universal Wall, but it is obvious that the limitations of contacts in moments
and the characteristics of chaotic information of universal wall cannot meet the needs
of campus relics collection. Hu Shoujun, a sociology professor at Fudan University,
believes it is necessary to keep lost-and-found sites in public places. “Setting up lost
and found points is actually a public service gesture.” [7]. If the team’s scan and pick
up items cabinet and reward mechanism can be successfully operated in the school,
it is also expected to be promoted to the society.
(2) Idle goods trading
On campus, there is a phenomenon that graduates have nowhere to put their idle
belongings and freshmen buy similar items. This is due to the lack of a convenient
second-hand trading channel on campus, resulting in a waste of campus resources.
There are second-hand trading apps such as “Poshmarklnc” and “Zhuanzhuan,”
but in the case of apps aimed at social people, students use them to change the
trading process into “campus-society-campus.” The social link in between is not
convenient. Because for student sellers, in the tight time before graduation, they
also need to do a good job in pre-sale and post-sale services, play with the trading
rules of the platform to increase commodity exposure, and find customers is very
difficult. For student buyers, the selection of campus transaction information in social

430 Y. Li et al.
software will magnify the shortcomings of trust and freight issues and reduce the
timeliness of the transaction. What our team hopes to build is a “campus-campus”
second-hand trading service platform. In the early stage of the project, our team
conducted a questionnaire survey among our students, among which the votes of “I
hope the school can provide a trading platform for idle goods” reached 100 percent.
This phenomenon does not only exist in universities, but also exists in all stages of
campus, selling books as scrap upon graduation, and borrowing books to ask the
neighbors. If it is effectively managed on campus, it is expected to spread to other
campuses.
(3) “research” path has you
This page focuses on the information of postgraduate entrance examination, includ-
ing the application information of postgraduate entrance examination school, public
curriculum materials and past experience. At present, students looking for graduate
school professional information is mostly consult teachers or search the Internet,
but the same professional students each postgraduate entrance examination experi-
ence is always of great reference significance to this year, yearning for the students
to consult the demand is universal. It is not limited to the experience of selecting
courses for postgraduate entrance examination, but also includes information about
whether certain certificates are necessary, employment and personal development.
In our survey, we found that the “yes” option of “willing to share your learning
experience or information” was selected 100%. This page is not limited to offline
time and place, can be very good for the convenience of students and teachers.
(4) Campus Notice
The page for the current information release in our school scattered port, informa-
tion is not centralized, not unified problems. In our school, the library, the General
College, the Student Union of the General College, the student union of each branch
and the society all have their own WeChat public accounts, which are numerous, but
few students pay attention to all of them. This leads to the problem of information
transmission. For example, the message of the public number is only displayed in
the column of the subscription number without a separate reminder. Inter-school
activities need to rely on a large number of people in the circle of friends to forward,
which is difficult to convey to students of different departments; Another example
is library opening and closing information and book update notification. At present,
the notification for students in our library is in one library QQ group, and the number
of students cannot be notified to all students. In addition, there is no proper platform
for teaching administration examination time and holiday notice to be effectively
communicated to teachers and students. The “Garden” applet is a messaging plat-
form that can centrally publish notifications and remind selected objects, making
campus notifications more convenient and smoother.
3 Develop the Advantage of Small Program of Technology Selection
The “Garden” mini program platform is mainly composed of online mini program oper-
ation, promotion, network security and offline coordination and management. The team
chose small program because of the high cost and cycle cost of traditional APP develop-
ment, which not only cannot generate traffic, but also needs to develop Android and IOS

Research and Development and Promotion of Campus 431
systems respectively according to the system. However, WeChat mini program is based
on WeChat terminal as the entry point. With the help of the promotion link of WeChat
simplified program, combined with the marketing advantage of WeChat public account,
users only need to click on the mini program to enter directly, without installation and
without occupying the memory of the phone. [8] Compared with APP, mini program is
more suitable for campus environment and has a dedicated channel for operation and
promotion, which greatly reduces operation cost. It is easy to operate so that students can
also undertake the small program online and offline docking tasks and management and
maintenance work. The platform’s promotion positioning is clear, can develop online
traffic, and has a strong pertinence, choose to develop small programs can also facilitate
the cooperation and promotion with various famous schools and students.
4 Technical Analysis of Program Design
In the development of the front end, the page layout of the small program is reasonable
has played a crucial role. In order to bring users a concise and efficient page design, we
plan to quickly define the elements through HTML, then use CSS to accurately posi-
tion the displayed elements, and finally use JavaScript to show the required effects and
interactions, so as to provide customers with a smoother browsing effect. [9] HTML5
and CSS3, as front-end framework applications, can adapt to various screen resolutions,
provide users with perfect dynamic design, and effectively increase the sense of user
experience. In the applets back-end programming api, the team plans to use the java pro-
gramming language, Spring Boot framework. Spring Boot infrastructure consists of three
files:src/main/java program development and the main program entry src/main/resources
configuration file src/test/java test program, which inherits the original excellent features
of Spring framework. The programming framework is shown in Fig. 1. It also simplifies
the process of building and developing Spring applications, making it easy to create
stand-alone Spring applications, or even create executable JARs and WARs through
the Maven or Gradle plug-ins. [10] The team will also use the MyEclipse development
tool, which combines the advantages of wide support and powerful functions to provide
great convenience for our subsequent small program development. Finally, we divide
the whole system into two parts: View layer and logical layer (App Service, based on
JavaScript), which can easily keep the running data in sync with the interface view. When
modifying data, we only need to make changes in the logical layer, and the view layer
will automatically adjust according to the data we modify and keep the synchronization
with it.
5 Business Model
(1). The operation of small program to attract and maintain the steady flow of people: one
is the functional aspect, demand-oriented: with small program lost and found, idle goods
trading and “research” way you and other convenient and practical and free functions
initially for small program to bring the flow of people; Then use the targeted message
reminder in the campus notice, continuously updated postgraduate entrance examination
information and other functions to maintain the steady flow of people; The second is

432 Y. Li et al.
Fig. 1. Programming composition, self-drawing
the technical design: the small program itself comfortable module layout and smooth
browsing effect, the user will not lose because of the sense of experience; Third, operation
skills: the team set up the point reward exchange link in the small program, users can save
points through the gift exchange or idle goods trading cash. This can form an effective
crowd control, increase the click-through rate and usage of the platform. Fourth, the
public welfare aspect of the mini program: the team will donate part of the profits of the
mini program to schools in poor areas with difficult teaching conditions. It can not only
respond to the call of The Times for youth responsibility, but also enhance the sense of
participation and enthusiasm of users. All of these details make Garden more engaging.
(2). Ways to make profits when operating small programs: with the flow of people
to have the flow of idle, we can make profits from it. First, in the trading section of idle
goods, the platform uses its own exposure to sell idle goods for students, which will be
divided according to the agreed proportion (the sharing fee will be no more than 3.5%).
The higher the proportion, the higher the exposure will be. The recommended commodity
column will be put into the merchant promotion, and the corresponding promotion fee
will be charged. Second, in the “postgraduate” process with your entrance examination
data section, we will gradually improve the fee teaching courses, but the team plans
to charge less than 30% of the profit, with a “small profit” business model to obtain
more long-term earnings. In the later period of the three mini programs, the advertising
rights may be opened. When users have the demand for points, they can obtain them by
watching advertisements, and the platform will charge merchants promotion fees. The
business process is shown in Fig. 2.
6 Specific Function Analysis and Design
(1) Lost and found
Release function: The finder clicks “I picked it up”, uploads the appearance photo of
the item, enters the location and time information of the item, and sets verification
questions. You can choose “scan code storage” to store in the transparent cabinet of
campus relics and inform the password to return, or make an appointment to meet

Research and Development and Promotion of Campus 433
Fig. 2. Business Model Flowchart, self-drawing
the place offline return. When a user claims and answers the verification questions
can be confirmed as the owner, you can claim the items in the agreed way. After
getting the item, the owner can click “I have found” to cancel the post (but it can be
found in the collection record), and can also evaluate the finder or report the extra
charge for offline transactions. After successful return, the finder will be rewarded
with points; (2) The lost click “I lost”, the release of lost items, can click on such
items to pick up the post message reminder. The finder can click “I found” to verify
the question. The lost can also browse for the lost items in the homepage post bar.
In the process of user operation, the platform will prompt the pickers not to divulge
detailed information, and provide automatic matching function of pickups according
to the pictures.
(2) Idle goods trading
The main page will have a search bar and a category view function, and the lower
part will show the highly publicized recommended products and promoted products
connected to the platform. When users have idle demand, click “publish”, select
categories, upload photos, fill in the item description and set the price. Sellers can
also spend platform credits to increase product exposure; Buyers can find what they
want through direct search or classified search. When purchasing, you can use the
platform points to offset cash. After placing the order, you can choose to meet and
trade or transfer the goods in the idle trading cabinet beside the lost and found cabinet.
After the transaction is completed, the buyer can evaluate the seller’s products, and
the seller’s platform with high evaluation scores will waive the exposure fee.
(3) “research” the way you
Postgraduate entrance exam information bar: The platform will organize and update
learning information classified by university, major and grade level for students.
Users can obtain it by searching on demand; Study information bar: Provide stu-
dents with the free download of PDF books required by the university’s popular
postgraduate entrance exam major. Playback links of open courses on CET-4, CET-
6 and postgraduate entrance examination by teachers are collected for students to
watch for free. Put into <30% of the platforms approved as excellent online course
promotion commodities; Experience question and answer area: students can post
questions, and choose to ask the crowd when Posting. After the platform reviews the
questions as meaningful, they can be pushed to such people. Users receive platform

434 Y. Li et al.
points for answering questions. Posters can set a comment to “helpful answers” and
earn extra points for that reply.
(4) Campus notice
After subscribing to the message notification function, ordinary users can receive
notification reminders released by the platform. Click on the alert or click on the
activity center to display a list of activities associated with that user. Click on the
activity to view the specific content of the activity, the time, the number of participants
and other information. Users can sign up for the event by clicking “participate”, and
they can get platform credits by punching in after the event.
The campus notice will invite the university library, the Dean’s Office, the Stu-
dents’ Union, the committee, the students’ Union and the student association. The
publisher can edit the founding activity by clicking the option of “Release Notice”,
select the department, major and grade to be notified, and then click Release. The
platform will alert the relevant user to view it, and the created activity will appear in
the activity center. The publisher can check the ratio between the number of visitors
and the number of readers or set the reply function on the visitor interface.
(5) Personal Center
Personal centers are divided into campus certification, my Pickups, my deals, my
notifications, my downloads, my Questions and Answers. Users can only use the
small program function after campus authentication, and relevant information can
be seen in the “My”.
7 Key Problem Solving
The key is to build a campus information smooth platform. Through the lost and found
interface, it can effectively unify the campus information of scavenged items, build an
efficient campus information release and return network of scavenged items, and infiltrate
the campus with positive information through the reward mechanism. Through the idle
commodity trading page, more campus resources that will be wasted can be fully utilized.
It helps students gradually form the environmental awareness of rational consumption,
green consumption and circular consumption, and provides them with a starting point to
respond to the national call for carbon emission reduction. Through the “postgraduate”
page, gather high-quality postgraduate entrance exam information, so that students can
quickly understand the accurate postgraduate entrance exam information for school
selection and follow-up study, to create a more focused campus learning atmosphere.
The campus notice page provides a more convenient platform for students to release
information, and solves the problem of low participation rate of current activities by
giving rewards after punching in. Finally, through the donation platform profit, so that
college students can also in the way of giving back to the society. The main solution
process is shown in Fig. 3.In short, this project attempts to analyze campus needs, so
that campus life can keep up with the pace of information technology, in order to create
a more convenient campus life style.

8 Conclusions
To sum up, “Garden” WeChat mini program platform can cover the campus in an all-
round way for all college students. The campus idle items, lost and found, postgraduate
entrance examination information, campus notice and other services integrated into one,
not only meet the needs of users but also facilitate the daily operation and publicity of
small programs. This small program is characterized by convenient, fast and effective
service, providing students with a comprehensive platform to effectively solve the actual
problems of students in school. “Garden” platform is based on WeChat mini program to
make more effective use of resources. The future development will be more inclined to
network and information, registration and authentication channels are fast, and WeChat
mini program will become more popular. There are infinite possibilities for the devel-
opment of campus mutual aid mini program “Garden”, and the future is very bright. It
is worth to further improve and expand, and create an influential public mini program
platform.
