Xiao, what are the three major cultivated lands?

The three cultivated lands of the old cow refer to the zodiac cow.

According to the traditional Chinese zodiac in China, the cow is one of them. In China, the Year of the Ox comes every 12 years. Therefore, the word "the old cow plows three fields" refers to the meaning of the Year of the Ox. The origin of this word can be traced back to ancient farming culture. Cattle play an important role in agriculture and are regarded as a symbol of labor force. Therefore, the three fields cultivated by the old cow can also be understood as the arrival of the Year of the Ox, which symbolizes the farmers' hard work and land cultivation in the new year, hoping for a bumper harvest season.
