Due to the references to many forbidden topics such as Dalai Lama, Winnie-the-Pooh and organ transplants in the season 23 (2019) episode "Band in China", since the episode's broadcast, South Park has been entirely banned in China: the series' Baidu Baike article, Baidu Tieba forum, Douban page, Zhihu page and Bilibili videos have been deleted or inaccessible to the public. In addition to this fact, all related keywords and topics have been prohibited from being searched and discussed on China-based search engines and social media sites including Baidu, Sina Weibo, WeChat public platform (微信公众号), etc.
