How to append path to begginig of every url for visitors from specific country or specific browser language via .htaccess

I would like to append zh-hans to beginning of every URL path, for visitors from specific country or visitors who use specific browser language.

In first I was able to redirect visitors from specific country or visitors who use specific browser language to desired URL, by adding this in .htaccess:

RewriteCond %{ENV:IP2LOCATION_COUNTRY_SHORT} ^DE$
RewriteRule ^$ http://example.com/zh-hans [R,L,NC]
RewriteCond %{HTTP:Accept-Language} ^de [NC]
RewriteRule ^$ http://example.com/zh-hans [R,L,NC]

How I want to path zh-hans be in front of every URL visitor from specific country or visitors who use specific browser language want to access.

For example:
If they want to access:
example.com/retailers or example.com/shop
I want them to be redirected to
example.com/zh-hans/retailers, example.com/zh-hans/shop…etc.

Thank you.
