Photo taken on July 18, 2017 shows four inside-painted glass snuff bottles created by Dong Xue, an inside-painting artist, in Shijiazhuang, capital of north China's Hebei Province. Inside-painted snuff bottle is a Chinese traditional handicraft. Inside-painting art, which has a history of more than 200 years, was also listed as one of the national intangible cultural heritages. Dong Xue and his daughter have continued to study the technique, and decided to pass on it. (Xinhua/Pu Dongfeng)
