Fan Shi, pronounced Xi Mungo, means: gifts and food gifts. Hold a feast ceremony. Modern people are used to having three meals a day. In fact, before Qin and Han Dynasties, people only ate two meals a day. Because agriculture is underdeveloped and food is limited, even two meals should be treated as people. Mozi Miscellaneous Harvest says that soldiers have two meals a day, and their food intake is divided into five categories.

The first meal is called "Chao Shi" or "Li" and is eaten when the sun reaches the southeast (corner). The second meal is called "Nian" or "Shi" and is eaten around 4 pm. For the time of eating, the ancients said that "food is irregular" (The Analects of Confucius). Eating when you shouldn't eat is considered as a polite behavior or a special reward.

After the Han Dynasty, two meals a day gradually became three or four meals. And the three meals are divided into breakfast, lunch and dinner. Breakfast, called cooler in Han dynasty, refers to snacks used after getting up and washing in the morning. In the Tang dynasty, cold weapons began to have the name of heart. "Notes on Neng Gai Zhai" said: "The secular case takes morning food as a snack, which has been said since the Tang Dynasty."

Up to now, breakfast is still called breakfast in many areas of our country. Lunch was once called "lunch" or "bento" by the ancients. Two meals a day, people think that "the sage and the people plow food, starting with food", and eating is a day's fault. Today, people often use the word "three meals a day" to express different feelings about time, including those who cherish time.
