creating a login page for each multilingual sub site
When I login via Filezilla, I will see jp, en cn directories denoting each language subsite. The site name would be /jp /en and so on. Each of this site has its own login,
Note the jp in the above URL. Now, I want to create a new language, zh for traditional chinese. I assume I would duplicate a language directory when I am logged into wordpress via Filezilla but how do I create
https://website/zh/bs/wp-login.php?loggedout=true&wp_lang=en_US (Note the zh)
I inherited this wordpress site so am not familiar with its structure.
