Taobao is China's largest consumer marketplace — the widest selection across every category. Tmall is its brand-store platform, where sellers are registered companies rather than individuals. Weidian is popular with independent sellers and small brands, so niche, pre-order and made-to-order items often live there. 1688 is a wholesale/B2B platform with lower per-unit prices but often minimum order quantities — best for bulk buys and materials. With BopoBuy you can paste a link from any of them, or search by keyword or image.
