The difference between red and yellow Douyin light boards is that the red light boards are for the top 10 on the popularity list, and the yellow light boards are for the fan groups.
The default color of fan light boards is yellow. Red light boards cannot be set separately. If you want a red light board, you need to be in the top 10 of Douyin's popularity list. The Douyin popularity list is updated every hour. As long as you rank in the top 10 of the list in any hour, you can get the reward of the fan light board turning red for a whole day. Douyin is a music and creative short video social software incubated by ByteDance. The software was launched in September 2016 and is a short video community platform for all ages. On January 18, 2019, CCTV and Douyin held a press conference to officially announce Douyin as the exclusive social media communication platform for the 2019 China Central Radio and Television Station Spring Festival Gala.
