The value of Wang Zhuo inkstone in Qing Dynasty

Wang Zhuo inkstone in Qing Dynasty was worth 20 million yuan. Cheng Niyan is one of the Han handicrafts and one of the traditional calligraphy tools in China. It began in the Han Dynasty and flourished in the Tang and Song Dynasties. It has a history of more than one thousand years. Since the Tang Dynasty, Duanyan, She Yan, Taohe and Cheng Ni have been called the four famous inkstones. Jiangzhou Chengni inkstone was founded in the Tang Dynasty (AD 6 18~907) with a long history and was once listed as a tribute inkstone.
