The history of watermelon cultivation:

China is the largest watermelon producing area in the world, but there are different opinions about the origin of watermelon. One theory is that watermelon does not originate from China, but is produced in Africa and spread to the Western Regions, hence the name watermelon. Another theory originates from the legend of Shennong tasting hundreds of herbs. According to legend, watermelon was discovered when Shennong tasted hundreds of herbs. It was originally called watermelon, which means a melon that is juicy and fleshy, but later it was passed down and became watermelon.

The more popular view is that the native place of watermelon is Africa. It was originally a wild plant of the Cucurbitaceae family, and was later artificially cultivated into edible watermelon. As early as 4,000 years ago, the Egyptians planted watermelons. Later, they gradually moved northward. Initially, they spread from the Mediterranean coast to Northern Europe, and then went south to the Middle East, India and other places. In the 4th and 5th centuries, they were introduced to China from the Western Regions, so they are called "watermelon".
