Douyin's "Mengzhi Plan" was launched in January 2021, aiming to support young knowledge creators in the long term. A relevant person in charge of Douyin said: "Culture and education have become important content categories on Douyin. We hope that through this event, we can work with creators to provide young people with safe and high-quality knowledge content, so that young people can discover the fun of learning knowledge while watching interesting popular science videos."

In the first two phases of the "Mengzhi Plan", many high-quality youth content creators have emerged. For example, the Douyin account "Zhizhi Popular Science" records popular science short videos for top scientists in the country to interpret cutting-edge scientific content. Among them, the collection of Academician Ouyang Ziyuan's explanation of aerospace knowledge has been updated to 82 episodes, which is deeply loved by young people. After joining Douyin, "Zhizhi Popular Science" has accumulated 2.18 million fans from scratch and received 8.1 million likes.
