子域上GET参数的Mod重写

I'm trying to rewrite a subdomain (NOT REDIRECT) to a $_GET parameter as such:

Desired result:

http://go.example.bz/link/abcde   ->   http://example.bz/go/link?id=abcde
or
http://go.example.bz/hrm/employee/8   ->   http://example.bz/go/hrm/employee?id=8

What's currently working:

http://example.bz/go/link/abcde -> http://example.bz/go/link?id=abcde
and
http://example.bz/go/hrm/employee/8 -> http://example.bz/go/hrm/employee?id=8

with this .htaccess in the root:

RewriteEngine On

RewriteRule ^go/link.php/([^/\.]+)/?$ go/link.php?id=$1 [L]
RewriteRule ^go/hrm/employee.php/([^/\.]+)/?$ go/hrm/employee.php?parameter=$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*)$ $1.php [NC,L]

AddCharset UTF-8 .php
Options -Indexes

and this is how I redirect the subdomain:

<VirtualHost *:80> 
   Servername go.example.bz DocumentRoot /var/www/go
</VirtualHost>

I do not want to redirect to the -> destination, rather to keep the http://go.example.bz/link/abcde url but have the results of the /link?abcde

I figured that my problem came from not remove .php extension from subdomain URLs of which I found an answer here https://css-tricks.com/forums/topic/remove-php-extension-from-subdomain-urls/ and then I alternated my RewriteRules as such:

RewriteEngine On

RewriteRule ^go/link/([^/\.]+)/?$ go/link.php?id=$1 [L]
RewriteRule ^go/hrm/employee/([^/\.]+)/?$ go/hrm/employee.php?id=$1 [L]

RewriteEngine on
RewriteCond %{HTTP_HOST} ^go\.example\.bz$ [OR]
RewriteCond %{HTTP_HOST} ^www\.go\.example\.bz$
RewriteRule ^/?$ "http\:\/\/tgc\.bz\/go" [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^([^\.]+)/$ $1.php

AddCharset UTF-8 .php
Options -Indexes

RewriteEngine On
RewriteCond %{HTTP_HOST} ^go.example.com
RewriteRule ^(.*?)/(.*)$ http://example.com/go/$1?id=$2 [L]

You can use this rule in root .htaccess:

RewriteEngine On

RewriteCond %{HTTP_HOST} ^(?!www\.)([^.]+)\.(example\.com)$ [NC]
RewriteRule ^(link)/(.+)$ http://%2/%1/$1?id=$2 [NC,L,QSA,R=302]

Does this help:

RewriteCond %{HTTP_HOST} ^go.example.com$
RewriteRule ^link/([a-zA-Z0-9]+)$ http://example.com/go/link?id=$1 [P]
