The oil-paper umbrella making technique is a traditional handicraft popular in Luzhou City, Sichuan Province. According to the "Lu County Chronicles", "Lu's (tung oil) paper umbrellas are quite famous. There are more than 20 families in the city. There are also many in the Chongyi Watershed, and the ones made in the Watershed are the best." The heyday of oil-paper umbrellas was from the late Ming Dynasty to the early Qing Dynasty to the 1970s. It is said that the umbrella was invented by Yun, the wife of Lu Ban in the Spring and Autumn Period: "split bamboo into strips, covered with animal skins, folded like a stick, opened like a cover", and the early umbrellas were mostly made of feathers, silk and other materials. The oil-paper umbrella actually appeared after the invention of papermaking, and began to be popularized among the people in the Ming Dynasty. Over the past 400 years, the oil-paper umbrella has evolved from a single rain and sun protection tool to an art piece for weddings, funerals, and ornamental decorations. In 2008, the oil-paper umbrella making technique was selected into the second batch of my country's national intangible cultural heritage list. The oil-paper umbrella-making technique in Luzhou City follows the traditional hand-made craftsmanship that has been used for hundreds of years. The raw materials of oil-paper umbrellas are mainly bamboo, tung wood, parchment and tung oil. From cutting to completion, an umbrella has to go through more than 90 processes and use hundreds of tools. Among all the processes, only a few processes such as drilling can use electric tools, which is considered to be free from manual work. The other processes are still completed manually. It takes about half a month to make an umbrella. The climate will mainly affect the shaping of the ribs and the flatness of the paper surface, causing bending or peeling. An umbrella can be repeatedly opened and closed 3,000 times without damage, soaked in clean water for 24 hours without falling off, and the top of the umbrella will not deform when walking in a level 5 wind.
