Who is the character in this avatar and which animation is it from?

Du Fu, a great poet in the Tang Dynasty, never dreamed that when he was 1300 years old, he would "resurrect with blood" in a place called the Internet, and he still appeared in various postures. These days, a group of pictures named "Du Fu is very busy" went viral in Weibo. The author has no way to prove it, except that some netizens processed Du Fu's illustrations in Chinese textbooks and sent them to Weibo, which triggered a series of spoof trends. Under the "polishing" of "collective wisdom", ancient poets who are concerned about the country and the people appear in various strange postures, sometimes riding motorcycles to go shopping, sometimes waving knives to cut watermelons, sometimes dancing the tango with Li Bai, sometimes flying dragons in World of Warcraft, and sometimes playing COSPLAY…… ... wearing the costumes of Shanghai Thief King, Saint and Gourd Baby ... People can't help laughing. Some experts think this is disrespectful to traditional culture, but most netizens think it is only a reflection of online humor. In this series of spoofs, Du Fu is actually the embodiment of various postures and mentalities of contemporary young people. They just "borrowed" Du Fu to express their inner thoughts.

Under the spoof of netizens, "Du Fu" became a flying witch.
