"Yin Bing" refers to Tik Tok's "Dong Shaotou Helmet Team". Every video of this team is basically wearing a white or red coat, a little sister Ling, and then the hairstyle is similar to a helmet. Holding a flower in my right hand all the time, I will put it back on when I shoot the video. The key is that the beauty effect is full and the characters are deformed.

Yin Bing is talking about Tik Tok's "Dong Shaotou Helmets". Every video of this team is basically wearing a white or red coat, and then the hairstyle is similar to a helmet. When shooting a video, I always hold a flower and a refill in my right hand. The key is that the beauty effect is full and the characters have been deformed, so they are called "Yin Bing Team" and "Yin Bing Out" by netizens.
