The so-called fire-painted gourd is a technique of painting on the gourd skin by heating a special copper needle and baking it on the gourd, drawing on the brush strokes of the center, side and side edges to express the Chinese painting techniques of hooking, rubbing, rubbing and dyeing. The fire-painted gourds can express a wide range of content, including figures, landscapes, auspicious patterns, calligraphy and other themes. The artistic quality of the gourds after fire painting has greatly increased, and even become the target of collectors. The inheritance of Niu's "Old Beijing Fire-painted Gourds" began with Bai Wensan, a descendant of Bai's disciples during the Xianfeng period of the Qing Dynasty. Bai Wensan, whose name is Guangning, is a Manchu and a bannerman. Wensan's father is Bai Er, a famous fire painter during the Xianfeng period. The son inherited his father's business and became famous for his father's art. His business was prosperous. In order to expand the business, the Bai family began to accept apprentices. It was at this time that Niu Guohe became an apprentice of the Bai family and began his career of fire-painting gourds. Niu Guohe, Manchu, Bordered Yellow Banner, courtesy name Bohan (1887-1956), began learning at the age of 13 and started working in Bai's fire painting business at the age of 19, and his fire painting skills became more and more mature. Later, Niu left Beijing and moved to many places, finally settling in Longwantun Town, Shunyi. After the reform and opening up, Niu Guohe and his grandson Niu Chengguo resumed their ancestral business and established the Beijing Jixiang Babao Gourd Handicraft Production and Sales Professional Cooperative, focusing on restoring the fire painting gourd skills. His fire painting gourd works have been widely praised in society.
