Meaning

UP主 refers to people who upload videos on video sites, a term imported from Japan. UP is short for "upload." Video creators on A站 (Acfun) and B站 (Bilibili) are often called UP主 by viewers, also known as "阿婆主." However, UP主 doesn't necessarily mean the original creator - reposters are also called UP主. On Bilibili, there are many famous UP主s with high recognition in various fields or unique perspectives.
