What's the difference between Ni Tianji video and Tianji book?

1, in different ways. Ni Tianji video tells users about book knowledge through video. Space-based books are taught to users through reading. So the two methods are different.

2. The content is different. Ni Tianji's video is brief and lasts for two hours. The gobbledygook is 48 sections long. So the contents of the two are different.
