[waruqi]

• Before adding new features and new modules, please go to issues to submit the relevant feature description first.
• Write good commit messages and use the same coding conventions as the rest of the project.
• Please commit code to dev branch and we will merge into master branch in feature
• Ensure your edited codes with four spaces instead of TAB.

---

• 增加新特性和新模块之前，请先到issues提交相关特性说明，经过讨论评估确认后，再进行相应的代码提交，避免做无用工作。
• 编写友好可读的提交信息，并使用与工程代码相同的代码规范，代码请用4个空格字符代替tab缩进。
• 请提交代码到dev分支，如果通过，我们会在特定时间合并到master分支上。
• 为了规范化提交日志的格式，commit消息，不要用中文，请用英文描述。

I think it should be fine. If you still need to improve, you can directly checkout and submit to this mouse branch.

I think it is ok, don't know how to test it, though
