AMA stands for Ask-Me-Anything, which means "ask me anything" in Chinese. It originated from the American social forum Reddit and is an interactive format where users leave questions, and the host answers them. AMAs can be categorized into: text-based AMAs, voice-based AMAs, and video-based AMAs. If you miss an AMA event that you're interested in, you can wait for the AMA Recap published by the organizers to read about it.
