About Us

Xian Mancang is a brand under Tongxi (Shanghai) Supply Chain Management Co., Ltd., focused on the full range of live, iced, frozen and dried seafood. Our business covers four lines — wholesale & delivery, catering & banquet supply, gift boxes & gifting, and live-holding consulting & support — providing supermarkets, wet markets, restaurants, banquet venues and households with one-stop seafood supply from source to table.

We are rooted in Shanghai Jiangyang Seafood Wholesale Market, at the heart of China's national seafood distribution hub. As the first stop for global seafood entering the country, our location — with flights and cold-chain trucks seamlessly connected — secures quality and price advantage from the source.

Backed by a mature cold chain and logistics system, we ship directly and efficiently across the country, delivering deep-sea freshness steadily to tables everywhere.
