What about Wang Qian? I saw Wang Qian on the Internet mainly for design. Do they have copyright?
The pictures in Qiantu.com are not copyrighted. Either it is not commercialized or it is authorized by the author through commercialization. Another option is to choose a copyrighted photo website for purchase. If vision china is too expensive, low-profit galleries like Yingku, Yi Shi and Yi Tu are a good choice.
