When the first king made the ceremony, the first consideration was to conform to the environment of the times, followed by ethics, then to distinguish objects and treat them differently, then to conform to human feelings, and finally to be commensurate with status.

For example, Yao passed the throne to Shun, and Shun passed the throne to Yu, which was the era of Zen Rang; And Shang Tang exiled Xia Wei, and King Wu of Zhou crusaded against King Yin, which was due to the situation.

The "Book of Songs" says: King Wen of Zhou built Fengyi, not in a hurry to realize his wishes, but to remember the deeds of his ancestors and show his filial piety.

Meaning, forced by the situation, it has to do this.

The sacrifice to the gods and the earth, and the sacrifice to the ancestors and ancestors, which embodies the way of father, son and son and the righteousness of kings and ministers.

That's a matter of shun.

The sacrifices of the shrines, the mountains and rivers, and the sacrifices of the ghosts and gods are different depending on the object of the sacrifice, and the number of rituals is also different.

This is the problem of the individual, if a family has a funeral sacrifice, it should have a considerable amount of expenses, and as relatives and friends, they should also give gifts to the mourning family, which is a matter of righteousness.

Although only a lamb or a piglet was used as a tribute, at the end of the sacrifice, each person who assisted the sacrifice received a portion of the sacrificial meat; And the sacrifice of the princes of the Son of Heaven, although it is a tribute of three sacrifices: cattle, sheep and pigs, but at the end, it is still a sacrifice meat per person, and there will be no leftover.

It's called being commensurate with status.

Princes could own turtles and treat them as treasures; It can be owned by Kei and regarded as auspicious.

And the doctor's house can't be like this, and the gate can't be built into a palace form.

This is also about the issue of identity.

Etiquette is sometimes more than more.

For example, the Son of Heaven has 7 temples, the princes have 5, the doctors have 3, and the scholars have 1.

For another example, the Son of Heaven can have 26 dishes, the duke only has 16 dishes, the princes only have 12 dishes, the upper doctor has 8 dishes, and the lower doctor has 6 dishes.

For another example, when the princes visit in person, they can bring 7 retinues, and as many as 7 prisons are given by the lord country; The princes' ministers can only bring 5 retinues when they visit, and only 5 prisons are given by the main country.

For another example, the cushion of the Son of Heaven has 5 layers, while the princes have only 3 layers and the doctor has only 2 layers.

Another example, when the Son of Heaven dies and is buried 7 months later, when he is buried, he uses 8 pieces of anti-wood and 8 coffin ornaments; The princes were buried after 5 months, and when they were buried, they used 3 layers of anti-wood and 6 coffin decorations; The doctor was buried after 3 months, with 2 anti-wood and 4 coffin decorations.

These are all examples of how more is more valuable.

Etiquette is sometimes less than is precious.

For example, the Son of Heaven went out on patrol and did not have a deputy.

The Son of Heaven sacrifices to the heavens, using only 1 cow.

The Son of Heaven came to the princes, and the princes only entertained them with one calf.

For another example, the princes hired each other, only served guests with fragrant wine, and did not set up large plates and small bowls of dishes; When the doctor comes to hire, the host country must not only have wine but also prepare dishes when entertaining.

Another example, when the Son of Heaven eats, he says that he is full after taking a bite, and he must be persuaded many times before continuing to eat; And the princes eat, eat two bites and say that they are full; The doctor and the priest ate and ate three mouthfuls and said they were full; As for the manual laborers who eat, there is no such Sven, when to eat and when to count.

For another example, the main road used by the Son of Heaven to worship the heavens only uses one circle of polyphery as a horse ornament, while the general secondary road uses five circles of polyphery as a horse ornament.

For example, Guizhang is the most valuable jade, which can be offered as a gift alone; Amber Juan, on the other hand, is a jade that is inferior to Guizhang, and cannot be offered as a gift alone, but must be offered with wine.

Demons and gods are more noble than humans, but only one layer of mats is used for sacrifices.

For example, when the princes are in court, and the number of doctors is small, the king salutes them one by one, and the number of scholars is large, and the king makes a collective gesture to them.

These are all examples of less being precious.

Etiquette is sometimes valued by the great.

For example, the size of the palace, the size of the vessels, the thickness of the coffin, and the size of the tomb are all precious.

However, at some point, the ceremony is more important than the small.

For example, in the temple sacrifice, the noble people use a smaller lord when offering the corpse, and the lowly person uses a larger scatter when offering the corpse; When the corpse came, the corpse was honored and raised a horn cup to drink.

Among the princes, when the viscount and baron feasted guests, in fact, the largest wine vessel was placed outside the door, the pot was a larger wine vessel and placed inside the door, and the tile (u) was the smallest, which was used by the king and the guests to get drunk, and was placed on the hall.

These are all examples of how small is precious.

Etiquette is sometimes precious.

For example, the hall of the Son of Heaven is nine feet high, the princes seven feet, the doctors five feet, and the scholars three feet.

For another example, only the gate of the princes of the Son of Heaven is a tall palace network gate, and the great doctors are absolutely not.

These are all examples of the high being noble.

Etiquette is sometimes low.

For example, when the Son of Heaven sacrifices to the heavens, the sacrifice is not held on a high altar, but is swept under the altar.

For another example, the princes of the Son of Heaven were not to use trays, the doctor's wine glasses were trayed, and the scholars' wine glasses were to be trayed.

This is an example of how low is expensive.

Rites are sometimes ornamental.

For example, the dragon robe worn by the Son of Heaven has nine patterns, the sacrificial clothes of the princes can only have seven five or three patterns, and the doctor can only have one black and blue pattern.

For another example, the crown of the Son of Heaven's headband is used to wear jade with a silk rope woven in vermilion and green, and there are 12 crowns, while the crowns of the princes are only 9, 7 for the upper doctor, 5 for the lower doctor, and 3 for the scholar.

This is an example of how ornamentation is precious.
