Hi @MSWuHe , welcome to Discussions
Here on this forum, we can only help in English. This is because we prefer to avoid automatic translation tools if we can, since they can lead to misunderstandings. Instead, we feel it is best for players to speak to our support agents (and other players) who speak their preferred language.
For support with Siege in Chinese, please follow this link: https://www.ubisoft.com/zh-cn/help/contact
If you'd prefer to continue here on the forum in English, that's fine too - just translate your post for us
