Bilibili is a Chinese online video-sharing platform that has evolved into a cultural phenomenon among the country's youth. Initially launched in 2009 as a niche community for enthusiasts of anime, comics, and games (ACG), it has since expanded to encompass a wide array of content, including music, dance, science and technology, movies, drama, fashion, and daily life videos. 

One of Bilibili's distinctive features is its "danmu" (弹幕) system, which allows real-time, overlaid comments to appear on videos, creating a highly interactive and communal viewing experience. This feature fosters a sense of shared engagement, as users can see and respond to each other's reactions both synchronously and asynchronously.

In summary, Bilibili serves as a multifaceted platform that blends user-generated content, interactive features, and a strong community focus, making it a central hub for young Chinese netizens seeking diverse and engaging online experiences.

Bilibili’s fan-driven culture encourages a strong tradition of sharing, often expressed through the meme Weiai fadian (为爱发电, “generate electricity from love”). In this regard, fan works are “labors of love,” and many creators on Bilibili produce AI-singing content not for profit, but out of passion. For instance, many users have uploaded tutorial videos (the one on the left is an example) that teach others how to use Sovits to create their own AI voice models. In the “What is Sovits” section, you’ll also find tutorials in multiple languages, making the process more accessible to a global audience.

As the homepage shows, many users openly share their AI Dongxuelian voice models, making it easier for others to create, remix, and build on existing works. This informal “Creative Commons” allows the community to thrive through collaboration and mutual appreciation.
