Generally, reliable websites do not judge the language based on the IP address (think about the situation of Americans traveling in China), but mainly rely on the prefered language set by the browser.

It should be because you have logged on. It is estimated that you have been using Chinese characters before. Even if your ip address is in the United States, your preferred priority should be higher than the ip address.
