There are different opinions about the name of "gourd": First, there are many varieties of gourd, which is a classification method of the ancients. For example, Lu Dian's "North Asia" thinks: "It grew up in the Tang Dynasty, but it is in the sun, short in the neck and big in the abdomen" and "like a round pot". He means that "fresh", "easy" and "Hu" are the names of three kinds of gourds, and their differences are mainly manifested in their appearance. The roe deer used as a dish is thin and long, like a loofah; That is, the gourd used by farmers as water hyacinth; The pot is an oblate gourd. But the classification of the ancients was not uniform. Li Shizhen's interpretation of the meanings of "Xie" and "Hu" is just the opposite of that of Lu Dian, that is, "Xie" is a flat gourd and "Hu" is a gourd ladle. Cui Bao thinks that Zan, Yi, gourd and gourd are not the differences between species, but the differences between species. He thinks "Zan" is the general name of all gourds, while "Xie", "gourd", "gourd" and "hanging Zan" are all Zan, but they are different in appearance. Second, the ancients thought that the nature and use of gourd were different, so the names were different. Some people think that in terms of its quality, gourd can be divided into sweet and bitter, and the sweet one is called "sweet" and "sweet"; Those who suffer say "baa", "baa" and "Shi Mao Lu Shu Yao Guang". As for "tea wine" and "medicine pot land", they are both named "Compendium of Materia Medica" because of their uses. Third, it is caused by the false homophones used by the ancients. Gourd not only has a long history of cultivation, but also is widely distributed all over the world. From the time recorded in the Book of Songs, China has cultivated gourds for more than 2,000 years. After the Book of Songs, there are more literatures about gourd. According to the statistics of "Ancient and Modern Books Integration" in Qing Dynasty, there are nearly 100 kinds of ancient books (articles) referring to gourd. In these books, some write about the planting method of gourd, some write about the edible, medicinal and daily value of gourd, some praise the poems of gourd, and there are a lot of myths and legends about gourd.
