+        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 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.

+        ### 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。
-        即使你在使用图形客户端/脚本/面板，也请遵照上述要求。
-        不要直接用“我使用xxx客户端/xxx面板”替代config，我们没有精力也没有义务去找到项目再花时间按描述重新问题。
+        
+        ### 对于日志
+        请先将日志等级设置为 debug.
+        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。
