Redirection problem

[ISAUD-HJI]

Whether it is the first login or N times, it is accessed

This page is not the /login page, after login, click the logo in the upper left corner will still jump to/this page When accessing the document, if you want to return to the /zh area, click the logo in the upper left corner will go directly to the/under so that users do not want to create a home page must also create a home page to enter the document
I hope the technical staff can answer my questions, thank you!
