Verify steps

• [X] I have read the documentation and understand the meaning of all configuration items I have written, avoiding a large number of seemingly useful options or default values.
• [X] I have not reviewed the documentation and resolve this issue.
• [X] I have not searched the Issue Tracker for the problem I am going to raise.
• [X] I have tested with the latest Alpha branch version, and the issue still persists.
• [X] I have provided server and client configuration files and processes that can reproduce the issue locally, rather than a desensitized complex client configuration file.
• [X] I have provided the simplest configuration that can reproduce the error I reported, rather than relying on remote servers, TUN, graphical client interfaces, or other closed-source software.
• [X] I have provided complete configuration files and logs, rather than providing only parts that I believe are useful due to confidence in my own intelligence.

@morytyann 只有一行就不要用ruleset了,没意义

[morytyann]

@xishang0128 那在文档里加一个ruleset必须大于一行？

[xishang0128]

@morytyann 处理了,等会用新的alpha就好了
