Going to clear up with how everything reached this point since that article failed to.
1. Last year in China there was a extremely popular TV show akin to "The Voice" but themed after hip-hop and rap. Kris Wu was one of the instructors on the show along with MC Jin.
2. PG One, one of the contestants on this show ended up winning this thing and garnered a huge following of fans as well as fame in a very short amount of time. He also joined a underground hip-hop group "Red Flower".
3. Sometimes around the start of January this year , PG One was photographed by paparazzi heading home midnight in the arms of a famous actress in China. (She's married to a famous actor)
4. Naturally this thing blew up around social media in China, soon followed by the media digging up all kinds of dirt on PG One: Copywrite issues with Marvel over using the name Magneto, drug use, songs that advocates drug use, sexual harassment, etc.
5. The government at this point started pulling those songs off the internet and blacklisted him in the entertainment industry. His more rabid fans went crazy and started attacking the government on social media and there was talks of self immolation in public places. The Red Flower group he joined was reported saying they wanted to topple the government.
6. So now the Chinese government flat out just banned the entire hip-hop culture.
