Farming can not only meet the needs of life, but also be used to strengthen the body and prolong life. Reading can affirm the truth and increase wisdom, which is the original intention of farming and reading. However, in later generations, the world mostly used farming and reading as the way to get rich. Cultivators are rich in fields. They go out early and come back late, busy with farm work. Scholars may not understand, but study hard for the imperial examination, and exchange knowledge and knowledge as capital for wealth.
Food and clothes are the necessities of people's daily life. Clothes are used to cover the body, keep warm and cold. Food is originally used to satisfy hunger, which is the original value of food and clothing. However, later people often show off their luxurious life through food and clothing. In a wealthy family, if you don't know that food and clothing are hard-won, you will catch the wind of extravagance from an early age. Those who cry roast meat and strive for money have long forgotten the original function of food and clothing. Such profligacy and lack of convergence will inevitably bring disaster.
