WeChat’s Decade of Innovation: Zhang Xiaolong on Video Accounts, Live Streaming, and Product Simplicity

During the 2021 WeChat Open Class "WeChat Night," Zhang Xiaolong reviewed ten years of WeChat development, emphasizing the core values of "connection" and "simplicity" that drive the product.

He described the birth of Video Accounts in 2017, how the team built a lightweight ID system to enable public video creation, and the challenges of integrating it with existing social and payment features.

Zhang explained the evolution of recommendation algorithms, noting early reliance on social (friend) likes, later incorporation of machine recommendations, and the importance of balancing content quality with user engagement.

The talk covered the rapid growth of video content, user statistics (e.g., billions of daily video calls, hundreds of millions of Moments posts), and the strategic shift toward video‑first content as a dominant medium for the next decade.

He also discussed live streaming, its low entry barrier compared to short‑video production, and future scenarios where live streams become personal expression tools integrated into user profiles.

Additional experimental features such as dynamic status, new emoji, and a potential WeChat‑branded input method were introduced, highlighting the company’s focus on continuous product innovation.

Finally, Zhang reiterated that WeChat’s success stems from building simple, connected infrastructure—ID, payment, mini‑programs, and video platforms—rather than merely adding features.
