The reason why there are so many mammoths in Zhuhai: Most of the mammoth raw materials that entered China through formal customs declaration channels came to Zhuhai from the Pearl River Delta region (Xiangzhou District, Doumen District, Zhongshan Tanzhou and Zhongshan Shenwan). There are not only a large number of large, medium and small processing plants here, but also a group of top tooth carving masters, which are wholesale and distributed in Guangzhou Hualin International and other places. Zhuhai has become the most influential production and wholesale base of mammoth craft products in China, and many jewelry merchants in Guangzhou Hualin and Wan Wen merchants are willing to pick up the goods all over the country.
