in 2019,using the "http://www.google.com/trends/?hl=en" can direct to english language on google trends,but when you type some words to search it return chinese again.
so there is another solution:
visit google account settings:https://myaccount.google.com
click Data & personalization-General preferences for the web-language,choose english and save
The problem vanished after two weeks, I don't know how (YT actualization maybe?)
I have actualized, reinstalled Chrome changed the account setting, etc. nothing's helped.
If someone has the same issue then it may be helpful that the problem hasn't occurred in other browsers.
