The tools we need are xshell (for setup on a computer), Juice
SSH (for setup on a mobile phone),
SSR (for rooted Android users), and Shadowrocket SS (for non-root users).
You can find xshell by searching on Baidu. Today I’ll post the computer setup method. Juice

The first step, of course, is to go to the Alibaba Cloud website.
Here is the site: https://www.aliyun.com/
Step 2  Click Free Package

Step 3  If you don’t have an invitation code, you can only purchase any product first.
We’ll choose to buy an OSS resource package.

Step 2: After entering the site, purchase an Object Storage OSS resource package.
It’s 9 yuan for one year; after entering, you can also choose the half-year package, which is 5 yuan.
PS: Without an activation code, you can only make a purchase~~~

Step 4: After purchasing, click ~Purchased, then go claim the free package·
You’ll see the trial duration~~that’s not important! What matters is below! All products in the free package
~~it turns out these actually need to be claimed!!
Claim the ECS cloud server, and after claiming it you’ll be taken to the page to create a host.

Step 5: Choose the region closest to your location.
For the image, choose CentOS 6.5 64-bit; of course, you can also choose 7.0 64-bit, but it must be 64-bit.
The other settings can stay at their defaults. To keep it short, the login name is root, and you set the password yourself.
Be sure to remember it; you’ll need it later.

Step 6  After creation is complete, click Console and find Instances.
You can see your server’s public IP there. Copy it down; that private IP is useless.
Just ignore it. Then download the xshell tool, install it, and open it.
You can find xshell by searching on Baidu.

Step 7: Open xshell, click File, New. For the name,
anything is fine. For Hostname, enter your public IP. Choose SSH as the protocol and port 22, then click OK.

Step 8: Enter the username root, click OK, then enter the password you set.

Step 9: Enter the setup script and press Enter: wget http://service.chuxen.com/SSR && bash SSR

Step 10  Choose the installation type. We choose multi-port, enter 2, then press Enter.

Step 11: Set the password and press Enter. Choose the port we need and press Enter. We choose
53 (for Aircard only), 138 (China Mobile free-data port), 80  8080 (China Unicom
and China Telecom free-data ports)

Step 12: Press any key, then the setup will start automatically and run through the code.

Step 13: Setup complete.

Step 14: Install SSR on your phone, then enter the server information in the SSR app: IP, encryption method,
remote port (any one of 53  138 80 8080), local port 1080, encryption
chacha20  protocol auth sha1  obfuscation method http simple, obfuscation parameter
optional. For Aircard, the obfuscation parameter is k.10010.com; for China Mobile, wap.10086.cn. 
 The phone access point can just use the default WAP. Then turn on the SSR app and test whether it is free-data.
You can search the IP on Baidu to see whether the IP address is the server IP. If the test shows it works,
you can also choose other servers. China Mobile works for me here,
so I bought an overseas server. The download speed is around 4 MB/s, and fq works smoothly without any pressure.
