A collector shows newly issued stamps featuring works of painter Liu Haisu in Suzhou city, East China's Jiangsu province, March 16, 2016. Liu (1896-1994) was one of the pioneers of the modern Chinese art movement, introducing Western art to China. Many also believe he was the first Chinese art educator to employ the nude in painting classes. The set of three stamps by China Post has a face value of 3.90 yuan (59 U.S. cents) [Photo/Xinhua]
