It's really hard to get rid of it. There is no special user search function, which is a deficiency of Baidu. I hope that Baidu developers can improve in time after seeing this problem.

Here is a method, not very good, but ok.

Enter in the search box on Baidu's homepage:

Baidu knows that "I only adopt Zhang Zhuoxian"

To explain, you must completely enter the contents of the above line, including double quotation marks, because this is called compulsory retrieval, which means searching Baidu for the same content as "I only use Zhang Zhuoxian".
