Li Liang, Vice President of Douyin Group, shared that the principles of recommendation algorithms for Douyin and Toutiao are not particularly unique compared to the Industry; the difference lies in the specific goals set for the algorithms by each platform, focusing on what is valued more. Douyin places greater importance on the Indicators of long-term user retention. It is believed that the term "information cocoon" appeared before the advent of recommendation algorithms, and from a business logic standpoint, the platform has no motivation to create the so-called "cocoon" and has the strongest motivation to break the "information cocoon." Li Liang also expressed that utilizing false information, extreme views, and polarizing rhetoric to gain traffic is something that Douyin continuously struggles against and addresses. He believes that ecological governance will ultimately benefit the healthy development of the platform.
