Nginx Specific Redirect Rules

Question

I'm trying to read all the suggestions and tips that are present in this forum but I cant find a way to make this rule work. I want that if a specific url is requested that nginx redirect permanently to a subdomain:

if ($host = 'www.domain.com/zh/')

    redirect www.cn.domain.com$requested_uri

The syntax its not correct but its only to give the main idea, I only want that /zh/ jump to sub domain, the other like /en/, /jp/, etc. I don't want nginx make any redirect.

Thank you very much, all help will be very appreciated.

This is pretty easy. You don't even need if.

rewrite ^/zh/(.*) http://www.cn.example.com/$1 permanent;
