Why are melons sweet in Jiashi County?

My hometown is Jiashi, which is a beautiful and rich place. My hometown is changing with each passing day, and technology is also developing with the changes of the times. Listen to my mother: in the past, Jiashi's houses were all built of clods, and people took dirt roads. When it rains, they become dirt roads, which brings inconvenience to people's walking. At that time, only wagons and tractors were used as means of transportation. Nowadays, Jiashi's buildings have sprung up, and the city has become much more beautiful than before, just like a little girl wearing new clothes! Now the roads are paved with cement asphalt. When it rains, people don't have to worry anymore. Cars, motorcycles and electric cars can be seen everywhere on the road, making it much more convenient for people to travel. My hometown has changed very much, very quickly. My hometown is also the hometown of melons and fruits, where there are sweet Jiashi melons and sweet and sour prunes ... There are many delicious foods in my hometown, such as special pilaf, delicious kebabs and delicious mutton offal ... I believe you will still want to eat them after eating. With the progress of society and the development of science and technology, people's living standards are constantly improving. Harvest! I believe your tomorrow will be better and richer. The beautiful and rich Jiashi welcomes friends from all over the world with his broad mind and unique charm.
