Welcome to the forum, fenggesaiwanbei.

The massive complex of Beijing’s Forbidden City and its Imperial Palace dominates the Chinese capital’s equally massive Tiananmen Square and is divided into two distinct districts, the Inner and Outer Cities.

I have coloured the subject of the (underlined) verbs red, and the predicate blue. The complex dominates Tiananmen Square and is divided into two districts.
