Plant legend
Watermelon, as its name implies, is a melon from the western regions. Five dynasties ago, it was not called watermelon because it had been introduced to the southeast coastal areas of China. Because of its cold and antipyretic nature, it was called cold melon. Therefore, it seems doubtful that watermelon was introduced into China from the Western Regions. So, how did it enter China? Presumably, it was introduced into China by the Maritime Silk Road.
Emperor Wu of the Han Dynasty once sent "translators" to raise businessmen, take silk and go to western countries by boat. The seagoing ship set sail from Leizhou Peninsula, sailed along the west coast of Beibu Gulf and the coast of Vietnam, bypassing Jinou Cape at the southern tip of Vietnam.
Then along the Siam Bay, along the coast of the Malay Peninsula, south to Singapore, and then west, across the Straits of Malacca, along the Bay of Bengal, to the country, "from then on, Chinese translation to English return" (Geography of Hanshu); This sea route is the so-called "Maritime Silk Road".
Where is "no country"? Most scholars think it is Sri Lanka, while others say it is Abyssinia in eastern Africa. No matter which statement is correct, it shows that the sea passage of China-Africa traffic has been opened in the era of Emperor Wu of the Han Dynasty. Because in the Han dynasty, Arabs had mastered the secret of the Indian Ocean trade winds and were able to sail through the Indian Ocean from east to west.
In this way, it is entirely possible for Sri Lanka and Nanyang Islands to become transit points between China and Africa. Watermelons from Africa can be introduced into China through Sri Lanka or Nanyang Islands. Watermelon seeds unearthed from Han tombs in Guangxi and Jiangsu are evidence of non-cultural communication in maritime Silk Road communication.
