Fake. Zhang Li, a teacher from Tik Tok, claimed to be the gold medal teacher of platform certification under the guise of Tik Tok's official platform. When paying Zhang Li, she will add Zhang Li's WeChat and send a video, but the video is different from the explanation. When she wanted to refund, she told the user that she could only refund half of the money according to the contract, or not. The money she cheated was 2950 yuan, which was fake and unreliable.
