The origin of paint can be traced back to 7000 years ago. During the period of 1978, archaeologists excavated a wooden bowl at Hemudu site in Yuyao City, Zhejiang Province. The exterior wall is painted with vermilion, which is slightly shiny and identified as paint, which proves that China had paint more than 7,000 years ago. In primitive society, people in China have discovered sumac trees and know how to use natural lacquer made from the sap of sumac trees as paint to increase the strength and life of articles. Before the Spring and Autumn Period, lacquer trees were widely planted in China, and officials in charge of lacquer gardens were set up. During the Warring States period, painters mixed tung oil with pigments to make colored pigments, which reduced the cost and improved the gloss. Traditional paint colors are mainly black, red, brown, yellow, golden yellow and green. In order to prevent the paint from cracking after drying, painters in Qin Dynasty invented the technology of drying in the shade with Yin Bao.
