The historical origins of kiwi fruit can be traced back to the Book of Poetry in BC. Tang Dynasty Nanyang people Cen Shanshiyun: "On the well railing of the atrium, a kiwi fruit". It is known that kiwifruit was already cultivated artificially at that time. Li Shizhen, a famous medical scientist of the Ming Dynasty, mentioned the shape and color of kiwifruit in his book "Compendium of Materia Medica" and described it as follows: "Its shape is like a pear, its color is like a peach, and the kiwi monkey likes to eat, so it has various names." "Tang Shenzheng said in the "Evidence-like Materia Medica": Sweet and sour, raw valley, vines and trees, round and hairy leaves, its fruit is shaped like a duck goose egg, its skin is brown, and it is luscious and edible after frost." This sour and sweet, fragrant and nutritious fruit has been sleeping for thousands of years, and human beings have really understood and used it for more than a hundred years, and have long been the "fairy fruit" food of monkeys.
Legend has it that in ancient times, in the southern forest area, a kind of fruit tree in the wild, people in the mountains do not know, its tree every year from August to October, the fruit ripe is oval, the skin has yellow-brown fluff, the appearance is ugly, people think that wild fruits are poisonous, they are contemptuous. One year, the mountain people unexpectedly found that when the wild fruit was ripe, the previous day he saw the wild fruit full of trees, but the next day only the bare tree poles remained, and there were no wild fruits falling on the ground. People were puzzled and thought: Where did so many wild fruits go? The following year, when the first-class wild fruit ripens, the people in the mountains take turns to watch it day and night. One night, it was the middle of the night, in the dim moonlight, people found: groups of old and young monkeys running from all directions, climbing to the fruit trees, you snatched the land to pick wild fruits, while eating and picking, snatching wild fruits for a time. People are talking about it: why do monkeys love to eat this kind of unseen wild fruit? When the wild fruit was ripe in the third year, the people in the mountains said, Since the monkeys can eat this wild fruit, can't we eat it? So, everyone went to pick and taste the fresh, first peeled off the peel, only to see the flesh colored as jade, sent into the mouth to try, it was sweet and sour, very delicious. Immediately, everyone took a large basket and a small basket, picked them one after another, and transported them home. The people of the mountains will eat the wild fruits they pick every day and every year. A few years later, since eating the wild fruit, the original body has become stronger, and the old and infirm have become light and long-lived. Therefore, everyone regards this wild fruit as a fairy fruit and a rare fruit. But this wild fruit had no name, so the mountain people held a meeting to discuss naming the wild fruit. At the meeting, everyone pondered but could not come up with a suitable name, and suddenly an old man stood up and said, my suggestion: According to this wild fruit monkey loves to eat; According to the color of the wild fruit, the shape is very similar to the appearance of a monkey; This monkey belongs to the macaque species; This wild fruit belongs to the fruit family Peach family. Based on this analysis, I think it is more appropriate to call it "kiwifruit". Through the discussion, everyone agreed that the name was good.
