Gongshu Aijing
The emperor makes a tour every five years: in the second month of each year, he goes to Mount Tai in the east to offer sacrifices to the mountains and rivers, and meets with the princes; he asks about those who have lived for a hundred years. He ordered the Grand Master to present poems to observe the customs of the people, and ordered the market to collect the money to observe what the people like and dislike, and whether they are lewd or rebellious. He ordered the ceremonial officials to examine the time and month, set the day, and standardize the law, and to correct the rituals, music, system, and clothing. If anyone does not raise the gods of mountains and rivers, he is disrespectful; if he is disrespectful, the king will reduce his land. If anyone does not obey the ancestral temple, he is unfilial; if he is unfilial, the king will reduce his title. If anyone changes the rituals and changes the music, he is disobedient; if he is disobedient, the king will exile him. If anyone changes the system and clothes, he is rebellious; if he is rebellious, the king will punish him. If someone has done good deeds for the people, he will be given land and improved the law. In the fifth month, the southern patrol guards will reach the southern mountain, just like the ritual of the eastern patrol guards. In the eighth month, the western patrol guards will reach the western mountain, just like the ritual of the southern patrol guards. In the eleventh month, the northern patrol guards will reach the northern mountain, just like the ritual of the western patrol guards. When returning, he will borrow from the ancestors and use special.
