The year after Confucius' death (478 BC), the state set the main hall where he lived as a temple. At that time, only three temples contained clothes, cars and ceremonies used by Confucius before his death. There were only three old houses of Confucius in the early days, and later generations worshipped Confucius in the humble old house and built houses according to the temple. The direct branch of Confucius is dedicated to Confucius, who originally lived in his hometown in Queli, and was called "Fengfeng House". With the rise of Confucius' position and the official position of his descendants, Confucius' home is expanding day by day. Confucius House is basically a building in Ming and Qing Dynasties, including 463 halls, halls, buildings and pavilions. It is a typical aristocratic gateway home in China, known as "the first one in the world".
