Walnuts for cultural and recreational purposes

Walnuts for cultural purposes are valuable collectibles formed by the selection and processing of special types and characteristics of walnuts.

Walnuts originated in the Han and Sui dynasties, were popular in the Tang and Song dynasties, and were popular in the Ming and Qing dynasties. Due to their unique appearance, they have medical and artistic value, and thus have collection value. Cultural and recreational walnuts mainly include three types: mahogany, walnut, and iron walnut, while mahogany walnuts also include lion head walnuts, Gongzi hat walnuts, official hat walnuts, chicken heart walnuts (i.e. the four famous walnuts), and tiger head walnuts. Cultural walnuts require deep and clear textures, with two walnuts having similar textures, consistent sizes, and equal weights. Walnuts become red after being played and gradually appreciate in value. Walnuts can also be made into stone carvings to enhance their ornamental value.
