Ginkgo, also known as ginkgo, is the kernel of ginkgo tree. Ginkgo tree, also known as gongsun tree and duck foot tree, is a dioecious gymnosperm among deciduous trees. As far back as 140 million years ago, in the Mesozoic Late Jurassic and Early Cretaceous, Ginkgo plants were in full bloom. Later, due to great changes in climatic conditions, the vast majority of genera and species have been cut off, leaving only two species like Ginkgo biloba and Ginkgo biloba. Up to now, Ginkgo biloba has disappeared, leaving only one kind of Ginkgo biloba, and only China grows and breeds. There are no living Ginkgo biloba in other parts of the earth, only its fossils can be seen, so Ginkgo biloba in China has the title of "living fossil".

Xing 'an and Lingchuan in Guilin, Guangxi, are between 280 and 600 meters above sea level, with four distinct seasons, moderate temperature, abundant rainfall and fertile soil, which are suitable for the growth of ginkgo trees and become one of the main producing areas of ginkgo trees in China. The ginkgo here is plump in fruit, tender and sweet in meat, and high in yield. It is also nearly one month earlier than other parts of the country, so it is well-known at home and abroad and has become a famous specialty in Guangxi, with an annual output of three or four million Jin, which is exported to Hong Kong and exported to Southeast Asia, Japan and other places.

Ginkgo fruit is harvested once a year. Small blue-white flowers bloom at the turn of spring and summer, bloom at night, and wither immediately after opening. The results will not mature until beginning of autumn. The skin and flesh of ginkgo are malodorous and poisonous, so they can't be eaten. The ginkgo we usually eat is the nucleolus of ginkgo. Ginkgo stone has two sharp ends, big middle, oblate and angular, three ribs are male and two ribs are female. Remove the shell and get the kernel, which is the edible part.

Ginkgo nuts are nutritious, containing 6% of protein, 2% of fat, 37% of sugar, and a small amount of calcium, phosphorus, iron and potassium. Ginkgo is cool, can be fried or made into sweets, and is the raw material of cool drinks. In hot summer, drinking a bowl of gingko porridge, gingko in sugar water or gingko ice juice will help to quench thirst and relieve summer heat. At the banquet, gingko soup, gingko pigeon eggs, gingko fish and gingko stewed duck are all delicious dishes.
