Chinese Xbox users do not have Chinese servers, only Asian servers. I guess they came from there.
(Perhaps they are unaware of the existence of Chinese forums)
In addition, simplified Chinese is more common in Chinese Mainland. If you write Chinese, it is recommended to use simplified Chinese.
中国的Xbox用户没有中国服务器，只有亚洲服务器，我猜他是从那里过来的。
（或许他们不知道中文论坛的存在）
另外简体中文在中国大陆地区更通用，如果写中文的话，建议使用简体中文。
