Introduction to Pingyang woodblock prints: Pingyang woodblock prints of the Jin and Yuan Dynasties were very famous in the early years. "The Sui Dynasty's Slim and Eminent Beauty", also known as the "Four Beautiful Pictures", was stolen by the Russians at the ruins of Heishui City in Xinjiang in 1907. It was later discovered by the Japanese in the Alexander Museum and published in 1929. There is no real thing in Dingcun now. The "Four Beauties" are four ancient beauties: Wang Zhaojun, Zhao Feiyan, Ban Ji, and Lu Zhu.
