Xianyu (Idle Fish) is Alibaba’s dedicated marketplace for second-hand and “idle” goods in China. It started from the simple idea of helping people clear out items they no longer use and has grown into a large C2C platform where users list products directly from their phones.
On Xianyu, someone’s unused smartphone, baby stroller, or limited-edition sneakers can quickly find a new owner. The app is closely connected with Taobao and Alipay, so users can log in with existing accounts and complete trades using familiar tools.
Over time, Xianyu has developed a strong community vibe. Young users treat it not only as a flea market but also as a place to share interests, side gigs, and a more sustainable way of consuming.
Key Features
Huge Pool of Idle Goods
Everyday Chinese users list items they no longer need: phones, computers, clothes, baby products, furniture, collectibles, and more. Rare or discontinued items are often available.
Strong Link with Taobao & Alipay
Many sellers originally bought items on Taobao and later resell them on Xianyu. Logins, order records, and payments reuse Alibaba’s ecosystem, making it convenient for domestic users.
Community & Lifestyle Feel
Xianyu hosts interest groups, city-based communities, and hobby circles. People trade goods and also share tips, skills, and small side-job opportunities.
Part of China’s “Reuse” Culture
Selling on Xianyu allows young consumers to recycle idle items, reduce waste, and earn extra money instead of throwing things away.
Advice for International Users
Xianyu is a popular Chinese second-hand C2C marketplace, but it currently only supports local payment methods such as Alipay or WeChat Pay. The platform does not offer returns or exchanges, so international buyers should exercise extra caution. Since the platform contains many dishonest sellers and even scammers, always use a trusted friend or agent in China to handle payments, and carefully check seller ratings and product details (including video verification). Avoid high-risk transactions and never transfer money directly to unknown sellers.
