How to change Apple 6p language back to Chinese?

The iPhone's App store will identify the country you filled in when you registered your iTunes account. For example, when you register your iTunes account "Country/Region" as a foreign country, the App store will recognize that it is displayed in English. Experts and colleagues changed the country's region to China through their own tests, which can really change the language displayed in the App store. To solve the operation method, I suggest you go to iPhone Settings-Store-Login to iTunes account, select "View Apple ID", select "Change Country or Region" as CHINA, click Next to read the terms of service (agree), and finally click Next to finish. This way, the App store can be displayed in Chinese.
