Photo taken on April 12, 2015 shows oil paper umbrellas at Fenshuiling township in Luzhou city, southwest China's Sichuan province. The history of Luzhou's oil paper umbrella production can be traced back more than 400 years to the late Ming Dynasty(1368-1644). Its craftwork is now a state-level non-material cultural heritage and has over 70 steps, including bamboo-splitting, drilling, threading, paper cutting, gluing and sun drying. [Photo/Xinhua]
