The art of Chinese bottle painting is one of the traditional arts and crafts skills. It began in the Jiaqing to Daoguang period of the Qing Dynasty, and Beijing was the place where it was discovered. There are four places in China, namely Beijing, Hengshui, Hebei, Boshan, Shandong and Shantou, Guangdong, where inner painting art is practiced. They are called Beijing, Hebei, Shandong and Guangdong. The techniques of the three major schools in the north were all introduced from Beijing. As the only representative of the Guangdong school, Shantou inner painting art has no traditional formal teacher-student relationship. Its founder is Wu Songling, a master of Chinese arts and crafts. Shantou bottle inner painting art is the only one in Guangdong Province and even in southern my country. It is unique in its unique glass bottle shape, gold and color decoration on the outside of the bottle, special painting techniques and colors, and painting tools. It is different from the other three schools and has formed its own style in the country. Inner painting is different from general painting. It uses the composition, brushwork and color of Chinese painting to paint on the inner wall of the glass bottle. Influenced by the Lingnan style of painting, the lines are relatively delicate, the colors are relatively rich, and the content is rich and colorful. It contains mountains, waters, birds and animals, ancient and modern figures, and exotic flowers in the bottle. It is known as the "unique painting art".
