Watermelon used to be called cold melon. Why did it change to watermelon?

Watermelon was called cold melon before because it was originally a cold fruit, so people at that time liked to describe it with the attributes of fruit when naming it. However, the talents at that time found that watermelon was not planted in the Central Plains, but came from the Western Regions. So the name of watermelon was changed to let people know that watermelon was introduced from the western regions, so that merchants at that time could sell it at a higher price.

In fact, there was no watermelon in the ancient Central Plains, but after the opening of the Silk Road, the trade between the Central Plains and the Western Regions became more and more frequent, so many foods and fruits from the Western Regions spread to the Central Plains. People in the Central Plains who eat watermelon for the first time feel very strange about it, because no fruit in the Central Plains has so much water and tastes sweet. So people at that time had a strong interest in watermelon, because watermelon had a lot of water, so people at that time began? Thin melon? So-called.

Thin? This word means that watermelon has a lot of water, and it was not until later that everyone finally figured out that watermelon came from the western regions, so they took a homonym and changed their name. In fact, watermelon, a kind of fruit, has high requirements on the planting environment. Watermelon likes warm environment. It can't stand high temperature and dry environment, nor can it accept cold climate. Therefore, watermelon is only suitable for planting in areas from 25 degrees Celsius to 30 degrees Celsius.

Although people at that time also wanted to introduce watermelons, the effect of introducing watermelons was not good because they had no experience in planting watermelons and the climate in the Central Plains was changeable at that time. However, during the period of the most frequent trade with the western regions, many businessmen from the western regions stayed in the Central Plains for a long time, and even finally settled in the Central Plains, so they slowly brought the technology of growing watermelons from the western regions to the Central Plains. That is, with the help of these people, talents in the Central Plains have successfully planted high-quality watermelons.
