-        Please check all of the following options to prove that you have read and understood the requirements, otherwise this issue will be closed.
-      options:
-        - label: I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
-          required: true
-        - label: I provided the complete config and logs, rather than just providing the truncated parts based on my own judgment.
-          required: true
-        - label: I searched issues and did not find any similar issues.
-          required: true

-        ## Configuration and Log Section
-        
-        ### For config
-        Please provide the configuration files that can reproduce the problem, including the server and client.
-        Don't just paste a big exported config file here. Eliminate useless inbound/outbound, rules, options, this can help determine the problem, if you really want to get help.
-
-        ### For logs
-        Please set the log level to debug and dnsLog to true first.
-        Restart Xray-core, then operate according to the reproduction method, try to reduce the irrelevant part in the log.
-        Remember to delete parts with personal information (such as UUID and IP).
-        Provide the log of Xray-core, not the log output by the panel or other things.
-
-        ### Finally
-        After removing parts that do not affect reproduction, provide the actual running **complete** file, do not only provide inbound or outbound or a few lines of logs based on your own judgment.
-        Put the content between the preset ```<details><pre><code>``` ```</code></pre></details>``` in the text box.
-        If the problem is very clear that only related to one end (such as core startup failure/crash after correctly writing the config according to the documents), N/A can be filled in for unnecessary areas below.

-        ## 配置与日志部分
-        
-        ### 对于配置文件
-        请提供可以重现问题的配置文件，包括服务端和客户端。
-        不要直接在这里黏贴一大段导出的 config 文件。去掉无用的出入站、规则、选项，这可以帮助确定问题，如果你真的想得到帮助。
-        
-        ### 对于日志
-        请先将日志等级设置为 debug, dnsLog 设置为true.
-        重启 Xray-core ，再按复现方式操作，尽量减少日志中的无关部分。
-        记得删除有关个人信息（如UUID与IP）的部分。
-        提供 Xray-core 的日志，而不是面板或者别的东西输出的日志。
-
-        ### 最后
-        在去掉不影响复现的部分后，提供实际运行的**完整**文件，不要出于自己的判断只提供入站出站或者几行日志。
-        把内容放在文本框预置的 ```<details><pre><code>``` 和 ```</code></pre></details>``` 中间。
-        如果问题十分明确只出现在某一端(如按文档正确编写配置后核心启动失败/崩溃)，可以在下面不需要的项目填入N/A.
