Folk artist Li Haiming makes an enamel drawing of the Four Great Beauties, four ancient Chinese women renowned for their beauty, in Peking Opera costumes in his studio in Lanzhou city, capital of Northwest China's Gansu province, March 7, 2017. It took Li almost half a year to make the work with a 20-meter-long wire that looks like gold thread. For nearly 20 years, Li has experimented with combining enamel skills with drawing, a process that usually involves time-consuming procedures. [Photo/China News Service]
