Extended information

Chopsticks originated in China and are one of the symbols of Chinese food culture, and serving chopsticks also originated in China. Whether it is sharing meals or using serving chopsticks, China has a long history.

As early as the Xia and Shang dynasties, "divided meals" had already appeared in China. In well-known ancient paintings such as "Banquet and Watching Dance", "Han Dynasty Mural of Dahu Pavilion in Mi County, Henan", "Han Xizai's Night Banquet" and other well-known ancient paintings, we can all see "separate meals": sitting on the floor and eating at separate tables.

In the Zhou Dynasty, which valued etiquette and law, the meal sharing system already carried the purpose of moral education. China's "shared meal system + serving chopsticks and serving spoons" has a much longer history than the "shared meal system".

In the civilized era, the meal-sharing system was once the way of eating for the aristocrats, and the people were also learning from the nobles' meal-sharing method, so the meal-sharing system became popular in the whole society.
