The Jiading bamboo carving technique is popular in the Jiading area of Shanghai. Jiading is located in the northwest of Shanghai, with Liuhe River to the north and rich in bamboo. The Jiading bamboo carving technique was created by Zhu He during the Zhengde and Jiajing years of the Ming Dynasty (1506-1566), and was mainly passed down in Jiading County (District). Zhu He integrated the art of calligraphy and painting into bamboo carving, and created the "deep carving technique" characterized by openwork and deep carving, making bamboo carving an independent art of appreciation. His son Zhu Ying and his grandson Zhu Zhizheng both inherited the bamboo carving skills of their predecessors and brought forth new ideas. Zhu Ying's knife skills are richer than Zhu He's, and Zhu Zhizheng's achievements have further surpassed his father and grandfather. His knife skills are magical, and his style is simple and elegant, simple and honest. The three generations of grandparents and grandchildren laid the basic character of Jiading bamboo carving art, and were called the "Three Zhus" in history. After the "Three Zhus", Li Liufang, Lou Jian and other "Four Masters of Jiading" also carved bamboo for fun in addition to calligraphy and painting. During the reign of Emperor Kangxi in the Qing Dynasty, Wu Zhi created a thin-ground positive carving method, which was graceful and vigorous, with varied layers, and was called "superb workmanship" by people at that time. There were also three brothers, Feng Xilu, Feng Xijue, and Feng Xizhang, who were good at round carving and figures. Their works were vivid and lifelike, pushing Jiading bamboo carving into its heyday. During the reign of Emperor Qianlong, there were many schools of Jiading bamboo carving, with Zhou Hao as the leader. Zhou Hao was the culmination of Jiading bamboo carving, using the knife like a pen, and his works were vivid and complete, and were called "the best works" by the world. Zhou Hao was as famous as Zhou Li and Shi Tianzhang, who were called "the three artists of Jiading" at that time. Jiading bamboo carving was sent to the court as tribute as early as the early Qing Dynasty. Emperors Kangxi and Yongzheng not only collected them, but also summoned artists Feng Xilu, Feng Xizhang, Shi Tianzhang and others to the inner court for worship; Emperor Qianlong wrote his own poems on the pen holder and asked Jiading bamboo carving artists to engrave them. In the late Qing Dynasty, Jiading bamboo carving was concentrated in Jiading City, with numerous workshops and shops. Shi Dajing's "Wenxiu Zhai", Han Yu's "Yunxia Room", Ye Duanfu's "Cuiqing Zhai", Zhang Xuehai's "Wenyuzhai", Zhu Houfu's "Youyangzu", Fan Yatang's "Wenyuan Zhai", Shen Zhuxiang's "Ruizhi Zhai" and "Pan Songyun Zhai" and "Xie Yinxuan" all had a certain influence, but at this time the entire bamboo carving industry had begun to stagnate and gradually decline. After 1949, Jiading bamboo carving had professional guild organizations and research institutions. Jiading bamboo carving has traditionally been passed down mainly through family and master-apprentice teaching. Many schools such as Zhu's relief carving school, Feng's round carving school, Wu's thin ground positive text school, Zhou's Southern School painting school, etc. have successors. The main inheritors of this skill now include Fan Xunyuan, Zhang Yingyao, Fan Qichang, Ding Liliang, Wang Wei, Wang Leping, Zhang Weizhong, Jiang Yuming, Su Yurong, Zhuang Long, Zhou Keng, Zhang Weizhong, Jiang Yuming, etc. Jiading bamboo carving artists use knives instead of pens, integrating various arts such as calligraphy, painting, poetry, prose, and seal carving, giving bamboo new life, making bamboo carving works have the atmosphere of books and the taste of gold and stone, elegant and unconventional, and becoming the elegant playthings of literati and scholars of all dynasties. The shapes of Jiading bamboo carvings are mostly suitable for the tastes of literati. Its varieties include pen holders, incense holders (incense), armrests, screens, and couplets made of bamboo tubes and bamboo slices, as well as figures, landscapes, plants, and animals carved from bamboo roots. Its techniques include more than ten types such as shallow carving, deep carving, thin ground positive text, shallow relief, deep relief, openwork, and round carving. It has a distinct regional style and distinct originality, and its aesthetic value far exceeds its practical value. Since Jiading bamboo carving is purely manual, the process is complicated, the production is time-consuming and laborious, it is difficult to form large-scale production, and the economic benefits are low, so most of the artists have changed their jobs. And no Chinese painters trained in art academies are engaged in bamboo carving. There is a lack of communication and exchange between calligraphers and painters and bamboo carving artists, which has led to the gradual loss of the cultural connotation of Jiading bamboo carving. In addition, with the pace of urbanization, large tracts of bamboo forests have disappeared, and the raw materials for bamboo carving have become scarce. All of these have led to the decline of Jiading bamboo carving skills, and measures are urgently needed to save them.
