What kind of sacrifice was used in the pre-Qin period?

In the pre-Qin period, ding was used for offering sacrifices.

The original tripod evolved from ancient pottery. The main purpose of tripod is cooking food. The three legs of the tripod are the stove mouth and the bracket. It can cook oil and cook food by fire under the abdomen.

Since the bronze tripod appeared, it has added another function and become an important ritual vessel for offering sacrifices to gods. Bronze tripod mostly has three legs with round abdomen and four legs with square abdomen. Dingkou has two ears. The possession and use of bronze tripod is one of the symbols of the status difference of slave owners.

In the Zhou Dynasty, there were regulations on the number of users, such as "Emperor Jiuding, seven diners of princes, five diners of Qing Dafu and three diners of Yuan". With the gradual evolution of this symbol of rank, status and status, Ding gradually became a symbol of kingship and a national treasure. Rulers often cast pots with the strength of the whole country. After Qin Dynasty, the symbolic meaning of Ding Wangquan gradually lost.
