Green coat can not only give people a visual feeling of healthy life, but also nourish the skin. Fresh and juicy red pulp is not only fragrant and pleasant, but also sweet and delicious, which can dispel the troubles brought by summer. Watermelon can be seen in the vegetable market in winter and summer. With the development of agricultural science and technology, more kinds of watermelons have been invented. However, the coordinates of the origin of this cheap and delicious fruit are not China, but semi-arid areas of Africa. The water stored in the desert can provide vitality and nutrition for its developed roots, and the continuous hot climate provides it with sufficient growth period and high sweetness. Unfortunately, locals regard it as a shame, but Europeans regard it as a treasure.

When the western powers expanded their territory in the world without restraint, many backward countries suffered from the disaster of plunder and slavery. Africans have been taken away from their homes, and the powerful labor force will continue to stay and cultivate the land for the looters for free. It's just bullying people's homes. Europeans find it unbearable to stand in the sun, not to mention the locals have to continue to pay physical labor. In order to maintain the yield of crops, whenever they are hungry or thirsty, predators will give them watermelons to eat. People in other areas that do not occupy territory will automatically associate watermelons with low grades, and the watermelons in their hands will suddenly become sugar-free.

Poor watermelon was rejected in the country of origin, but in the hands of Europeans who know how to enjoy life, it has become a treasure that only nobles have the opportunity to taste. After being introduced into China through trade, it took root in the fertile Central Plains. The unique geographical conditions and mature planting techniques ensure the output of watermelon, and the people also take it orally when the price comes down. Although watermelon is delicious, it is not recommended to eat more from the perspective of health, especially those with cold constitution should be more cautious.
