Recently, Tik Tok launched the "Galaxy Knowledge Project" to encourage creators to create knowledge collections for young people and present knowledge videos in a systematic way to further stimulate their curiosity and creativity. The program will invest billions of flows to support high-quality creators, and high-quality content will be recommended by Tik Tok Learning Channel and Tik Tok Youth Model.

"Knowledge Collection" refers to a series of video searches that explain knowledge content around a certain topic. Through the function of "collection", videos are presented logically, structurally and coherently. Relying on the content framework established by the creator, users can systematically acquire knowledge increments.

Taking the description of Tik Tok in Natural History magazine as an example, in the collection of knowledge about owls in the night sky, the creators popularized the habits and characteristics of different types of owls, such as barn owls, carved owls, snow owls and Wulin owls, to help teenagers understand them from multiple angles.

It is understood that the first phase of the "Galaxy Knowledge Plan" will launch sub-topics such as "Bright Science Star", "Deep Culture Star" and "Smart Life Star", covering knowledge popularization, traditional culture, animals and plants, aerospace, mental health and other fields.

Huang Zheng, an associate professor at the Institute of Psychology, Chinese Academy of Sciences, believes that "from a psychological point of view, strengthening the coherence between knowledge videos can make more and more complex knowledge clear and refined, help teenagers to establish an orderly knowledge structure, and be more conducive to understanding. Through the presentation of Tik Tok's portfolio, it can also help young people quickly find the connection between the skeleton of system knowledge and knowledge, which is more conducive to memory. "

Ji Lianhai, the original speaker of Lecture Room, moved the national treasure to Tik Tok with the theme of "The Story Behind the National Treasure". Yang Xiaoyang, the invited creator of Popular Science China, takes young people to appreciate the rich plant world; Ning Dawei, editor-in-chief of Chinese audio content of the national marketing calendar, learned about the interesting and romantic Winter Olympics in 5 minutes.
