Youtangshe, also presented as Yuanqi Duotang House, is a Chinese-language website that organizes and shares collections of high-resolution portrait photography and related visual content. Its catalog brings together material associated with numerous photography studios, image publishers, and creator brands, with categories covering Korean collections, Chinese portrait series, cosplay, street photography, and other themed shoots. Listings describe individual releases and commonly include image or video counts, file sizes, and publication dates, helping visitors browse the archive.

The site says its purpose is to share quality materials and enjoyment, and notes that some resources are available for free; it also promotes downloads and provides guidance on navigation, extraction, and downloading. Its pages feature frequent resource updates, searchable categories, and links to a broad range of collections. The website advises visitors to follow the laws that apply in their country or region when downloading or viewing resources.

Overall, Youtangshe functions as a large directory and distribution site for downloadable photography and video collections rather than as a photography studio producing original work
