Clubhouse is blowing up in China, but many Chinese-speaking users aren't talking. Instead, they're using it to network.
One chatroom is named "Silent Room 2: No talking on the microphone, just checking bios and following each other" in traditional Chinese script. It's attracted over 1,700 participants, including the famous Taiwanese singer and actor Aaron Yan. Even with over 80 people set as speakers or moderators, the room is dead quiet.
The purpose of silent rooms is for users to network and make as many friends as possible without uttering a word. For many participants, a glossy well-written bio is enough to earn new followers.
