Zhongnanhai is a former imperial building in Beijing, China that serves as the office of the General Secretary of the Communist Party and other top leaders of China. It appeared in Season Nineteen episode "Tweek x Craig".
Background
CCP general secretary Xi Jinping received a phone call from Randy Marsh, who asked how his people decided who is gay or straight. Xi tells Randy that Yaoi comes from Japan, but as Stan walks in, Randy pretends over the phone that he knows what he is talking about. In response, Xi goes on a rant against Japanese people.
In the montage towards the end of the episode, Xi Jinping was seen in his office kissing with his secretary, following the restoring of relations between Tweek and Craig.
