On the one hand, there is publicity that the course is a free five-day learning video clip, claiming that even novice Xiaobai and zero fans can make money through the course, and asking for 2,880 yuan in tuition fees to provide methods and materials. However, some students who actually participated in the course reported that the content of the course was mainly recorded and broadcast after payment. After operating according to the teacher's method, the expected broadcast volume and fan growth were not realized. On the other hand, some data show that Beijing Tianling provides free adult video editing courses, aiming at helping students master video production skills from scratch. The course covers the basic knowledge of video editing, picture adjustment and beautification, subtitles and watermarking. However, there are also objections that it is difficult for students to get in touch with relevant personnel after the course fees are charged, questioning the effectiveness of the course.
