The origin of rice

According to historical speculation, rice was planted about 50,000 years ago and was first discovered in our present Yunnan area. According to modern records, it is the middle and lower reaches of the Yangtze River that began to grow rice, which is what we now call the land of fish and rice. The Yangtze River is rich in geographical resources and is very suitable for growing rice. In many areas, seeds are sown twice a year.

According to different regional soils, the varieties of rice planted are different, so we usually buy many kinds of rice in the market. In fact, it takes a very complicated process to change rice into rice. From the beginning of sowing to the mature harvest, the whole time and manpower are great, and the process is also very long and arduous.
