Hi @zhuhongboAAA, thank you for making the changes!
While you were working on this, the original English page for dd.md was updated in a separate pull request. The bot has correctly noticed that this translation is now slightly out of date.
Specifically, sudo was added to several examples, and the last example was changed.
Could you please make the new changes to match the updated English page?

嗨,@zhuhongboAAA,谢谢您做出这些改变!在处理此内容时,dd.md 的原始英文页面已通过单独的取款请求进行了更新。机器人已正确注意到,此翻译现在已略有过时。具体来说,在多个示例中添加了sudo,最后一个示例被更改了。您能尝试进行新的修改以匹配更新后的英文页面吗?

Great job getting this done! Thank you for working through the updates to match the English page.
