Summarizing the relevant rules and reasoning
I found useful excerpts from the webpage: Line 155 talks about commercial solicitation, which aligns with option C. Line 181-183 reinforces rules against discrimination and insults, supporting options A and D. Additionally, Chinese law on defamation backs D. So, the correct answer is A, C, and D, along with citations from the Douyin convention.
