According to historical records, my country's ivory carving technology has a history of more than 3,000 years. The appearance of Guangzhou ivory carving is slightly later than that of the Central Plains. It began in the Jin Dynasty and has a history of more than 2,000 years. Among the cultural relics unearthed from the tomb of the Nanyue King in the Western Han Dynasty, there is a bundle of 5 large tusks, the largest of which is 126 cm long. According to identification, the origin of ivory is Africa, and it may have been transported via the Maritime Silk Road. In addition, carved pictures, ivory abacus and broken ivory carvings were unearthed. It can be seen that these ivory were imported as raw materials for carving. If the identification is true, then the history of Guangzhou ivory carving will be greatly pushed forward. In the past, people in Lingnan, especially those in Guangzhou and the Pearl River Delta, regarded ivory as a lucky thing. They believed that it could "ward off evil and remove filth." The ivory carving introduced here refers to ivory carving. Guangzhou's ivory carving flourished in the late Ming Dynasty. After development through the ages, it gradually became a famous specialty of Guangzhou. Before liberation, Guangzhou's ivory carvings were all operated by individual workshops, mainly concentrated in the Daxin Road area. After liberation, in order to carry out research and development in an organized and planned manner, and to improve and develop the art of Guangzhou ivory carving, the Guangzhou Municipal Government organized these small workshops into the "Daxin Ivory Carving Craft Factory". Since then, the skills of ivory carving have made significant progress, and the scale of production has also expanded. Guangzhou's ivory carvings have both strong oriental ethnic colors and exquisitely carved Lingnan style. They are mostly based on Lingnan landscapes such as flowers, trees, rocks, dragon boats, pagodas, crab cages, etc., and are good at unique hollowing techniques. Among them, hollowed-out ivory balls and painted boats are famous, especially the finely carved multi-layer ivory balls. The carving artists use a piece of intact ivory material to hollow out balls of various specifications and different numbers of layers. The smallest ivory ball has only two or three layers, and the largest has more than 40 layers. Each layer is engraved with various patterns such as dragons and phoenixes, flowers, etc., and can be flexibly rotated. The 20-layer ivory ball carved by Guangzhou ivory carving artists won the special craft award at the Panama International Exposition in 1915. So far, the number of carved layers of Guangzhou ivory balls has reached 45. Pavilions and flower boats are also famous Guangzhou ivory carvings. The hull of the flower boat is shaped like a dragon and has 27 floors. There are as many as 3,000 people on the boat, as well as flags, lighting, etc., which are lifelike and in various poses, very spectacular. In addition, there are full ivory carvings made of whole ivory, fishermen casting nets, crab cages, and ladies in ancient costumes. Guangzhou ivory micro-carving is also famous throughout the country. In the early 1930s, Feng Gongxia, a famous Guangzhou micro-carving artist, carved the full text of Mr. Sun Yat-sen's will in 154 words on an ivory grain as big as rice. He also carved the 25,000-word "0 Declaration" on an ivory sheet the size of a 64-page paper. His son Feng Shaoshi is also a master of micro-carving. He inherited his father's skills and created the 18 Arhats with different images and lifelike on a grain of ivory. These exquisite micro-carvings represent the highest level of Guangzhou ivory micro-carvings and are breathtaking. In the 1980s, due to the global movement to protect wild animals, elephants were protected wild animals and hunting was strictly prohibited. International regulations stipulated that no country could sell ivory and ivory products, and the Chinese government strictly abided by this regulation. Under such circumstances, Guangzhou's ivory carving craftsmanship, especially the ivory carving industry, suffered a serious blow and had to use other materials instead, barely allowing this traditional craft to continue. The 45-layer ivory ball and the pavilion and flower boat have become unprecedented and unique art treasures and unique works in the world.
