5. Download links and usage tutorials are available on this page (using Windows as an
example). Please follow each step carefully.
下载链接和使用教程均在此页面（以 Windows 系统为例），请耐心做完每一
个步骤
6. After completion, go to My Wallet to top up your balance. (Note: The VPN will not
be usable until you top up; this is normal.) We recommend choosing the 30-yuan
3-month plan (300GB per month), which offers the best value for money.
完成后进入我的钱包进行充值，
（注意：未充值前 VPN 是无法使用的，这是
正常现象）建议选择 30 元 3 个月（每个月 300GB）的套餐，性价比较高。
7. After completing the top-up, restart the VPN. Once the configuration steps in the
tutorial are finished, enable the “System Proxy” to activate the service. (Note: The
VPN is a network functionality product, not the network itself. Therefore, an internet
connection is required each time you use the VPN—meaning both the VPN and the
internet must be active simultaneously. Campus networks, personal mobile hotspots,
or mobile data plans can all be used alongside the VPN.)
充值完成后重启 VPN，完成配置（教程中的步骤）后打开“系统代理”方可
使用（注意：VPN 是网络功能型产品，不是网络本身，所以每次使用 VPN 的时
候也需要有网络为基地，即二者一起使用而不是只打开 VPN，校园网、个人手
机热点、流量均可与 VPN 配套使用）。
8. The core functionality of this course requires the proxy feature within the app
interface. Please select nodes accessible via Classcompanion.com (Professor’s
recommendation: USA). If you encounter other suitable options, you may use them
independently.
此课程最核心的功能需要是 APP 界面里的代理功能，请选择可以使用
Classcompanion.com 的节点接入（教授推荐：USA 美国），如果遇到其他合适的
也可自行使用。
9. This VPN offers all the features of other VPNs. With the system proxy enabled,
users can also access academic external network resources (such as Google Scholar),
use foreign media platforms (like Instagram), and log into overseas academic systems
(such as graduate school application websites). A single account can be shared across
multiple devices (currently up to five). Sharing the VPN does not impact academic
output, as the VPN functions solely as a network proxy. Each user's activities and
contributions on Classcompanion remain independent of the VPN. Therefore, account
sharing is permissible. However, to prevent reaching the user limit (e.g., one student
using two computers and three phones), it is recommended that each individual
maintain their own account.
此 VPN 具备其他 VPN 的所有功能，系统代理开启状态下用户还可以翻阅学
术外网资源（如 Google Scholar）、使用外媒（如 Instagram）、登录国外学术系统
（如国外研究生学校申请网站）等。一个账号可以由多个设备共享（已知是五个），
VPN 共享并不影响同学们的学术产出因为 VPN 只是网络代理，每个用户在
Classcompanion 上的行为与产出与 VPN 无关，因此同学们可以共享账号，但是
为了防止 VPN 达到用户上限（比如某位同学有两台电脑和三部手机），还是建议
大家人手一个账号。
