What plagiarized works of art are there at home and abroad?

Ceng Fanzhi's oil painting Leopard was sold at Christie's Spring Auction "Asian Twentieth Century and Contemporary Art" in Hong Kong for HK$ 36 million. Late at night on the 29th, Xi Zhinong, a famous wildlife photographer, broke a picture of a leopard in Weibo, which was exactly the same as a picture of a snow leopard taken by Steve Winter, a British National Geographic photographer, causing a heated discussion. Many netizens pointed out that Ceng Fanzhi was suspected of plagiarism and was wronged by the buyer, but some painters pointed out that "this technique of painting oil according to photos is a normal practice in the field of contemporary art, and netizens will question it because they don't understand it."
