Walnut culture in China, the hometown of walnuts.

Tan Cui, a native of Anwei in Qing Dynasty, said in Heng Zhi of Yunnan Haiyu that walnuts stand on Yangbi River, and their shells are thin and can be broken by pinching. Yangbi County, located in the west of Dali County, is famous for its rich walnuts. If you visit the Yi people's home in Yangbi mountain area, they will certainly treat you with local traditional food walnuts dipped in honey. This is a sweet and delicious food that moistens the lungs and eliminates phlegm. Yangbi Walnut is one of the important export commodities in our province because of its large fruit, thin shell, kindness, fragrance and high oil yield. Yangbi mountain area is full of lush walnut forests. Walnut trees are stout and tall, with many centuries-old trees. There is a walnut tree in the high-risk brigade of Pingpo Commune, which is two meters in circumference and graceful, covering an area of half a height. Generally, the annual output of walnuts is more than 2 kilograms, and it can extract nearly 7 kilograms of oil. This tree is called the Walnut King. Walnut kernel is high in oil content, which can be squeezed and eaten raw and cooked. Traditional holiday foods in Dali, such as the Lantern Festival in the Spring Festival and the moon cakes in the Mid-Autumn Festival, are filled with Yangbi walnut kernels, which are crispy and sweet. Yangbi Walnut is also a gift for relatives and friends.
