Color painting has a long history in Dongping. People first painted pictures on buildings. With the development of religious undertakings, various patterns representing religious meanings were vividly painted on buildings and walls. The painted patterns often have specific religious themes and meanings, which serve to decorate religious buildings and add a solemn and sacred color to religious buildings. At the beginning of the 21st century, a new form of color painting appeared, which painted colorful patterns on gourds and lotus seeds, becoming a new art form. Representative figures in color painting include Hou Qingpei. At the end of the 20th century, in order to inherit and develop folk art, Hou Qingpei used the calcified, thick, lubricated and shiny characteristics of Dongping Lake Mallard Duck Eggs and its resource advantages to develop a series of colored egg products, which were welcomed by tourists. In 2004, Hou Qingpei used traditional Chinese painting techniques and combined them with modern scientific processing. He used lotus seeds from Dongping Lake to draw lifelike 108 heroes of the Water Margin on the small lotus seeds, and overcame problems such as insect infestation, mildew, deformation, cracking, and dehydration. The eight characteristics of "elegance, vulgarity, novelty, beauty, uniqueness, convenience, storage, and circulation" were applied for as a national patent and became a collection of the Shandong Provincial Archives. In August 2010, it was announced as the second batch of county-level intangible cultural heritage list. In December 2010, it was announced as the third batch of municipal-level intangible cultural heritage list. (No pictures yet, welcome to provide.) (No pictures yet, welcome to provide.)
