Weipaitang is a Chinese e-commerce platform for antiques, collectibles, and cultural artwork, operated by Hangzhou Weipaitang Cultural Creativity Co., Ltd. Launched in 2014 and headquartered in Hangzhou, it helped bring live auctions of collectibles online. The platform connects buyers and sellers through livestream bidding, consignments, and resale services, offering a way to discover, purchase, and sell items such as coins, antiques, and other collectibles.

Weipaitang also provides free appraisal services, including one-to-one livestream consultations with experts and professional review of items such as luxury bags, amber, and beeswax. Its AI recognition feature, introduced through its app and mini-program in 2024, helps users identify and check prices for categories including coins. Sellers can use managed consignment, item inspection, and resale services, while merchants can join the platform to reach a large audience and host auctions. Community features let users share interests and learn about collecting. The company says it has introduced consumer-protection measures and service standards for online collectible auctions.
