A sign prohibiting picking melons.

Nowadays, cucumber has long been a common food on people's table. I don't think the name cucumber is entirely worthy of the name. Cucumber is indeed green in the growing period and picking period, but when cucumber gets old, the skin color of cucumber will gradually turn yellow. People usually eat and use all green cucumbers, and all these cucumbers are not really mature.

Really mature cucumber, its skin is really yellow, even the melon seeds are yellow. But why do people eat immature green cucumbers? The results showed that the skin of fully mature yellow cucumber was very thick, and the taste was very poor at the entrance, which was far from the delicious crisp mouth of immature green cucumber.

Therefore, people always pick and eat cucumbers before they are ripe or tender green. Over time, yellow cucumber was replaced by green immature cucumber in the market. Therefore, people always think that cucumbers are green.

In addition, there is a story about the origin of cucumber. It is said that cucumber was originally called cucumber, and this kind of cucumber is not necessarily a native product of the Central Plains, but a kind of fruit and vegetable brought back from the Western Regions by Zhang Qian, who was well-known in the Han Dynasty when he sent various cultural exchanges to the Western Regions.

However, the Jie people in the western regions don't like being called conference semifinals by others. Therefore, after the establishment of the post-dynasty, the Jie people banned the use of Hu characters, which was also very common in ancient China.
