Watermelon, as the name suggests, is a melon from the Western Regions. Five generations ago, since it has been introduced to the southeast coastal areas of our country, it is not called watermelon, but because of its cold and antipyretic nature, it is called cold melon. Therefore, it seems questionable that watermelons were introduced to China from the Western Regions.
So, from what route did it come to China?
It is speculated that it was introduced to China by the "Maritime Silk Road". Emperor Wu of the Han Dynasty once sent a "translator" to recruit businessmen, carry silk, and take a sea ship to Western countries to "city pearls, bi liuli, strange stones, and foreign objects." The sea vessels set sail from the Leizhou Peninsula, sailed along the west coast of the Gulf of Tonkin and the coast of Vietnam, bypassed the southern tip of Vietnam, and then along the Gulf of Siam, followed the coast of the Malay Peninsula to the south, arrived in Singapore, and then turned west, crossed the Strait of Malacca, and arrived along the Bay of Bengal to the country of Chengbu. This sea route is the so-called "Maritime Silk Road".
