What rituals did the Tang and Song dynasties inherit from the Northern Qi?

The leading flag of the army was called "the flag of the teeth", the division must be sacrificed, and the ritual of sacrifice was also named "headboard", with a special "headboard ceremony". The barracks must establish an altar, wrapped with a green rope, with a curtain and a tent, where the military teeth and the flag's tablets are placed. Sacrifices should be made with a full set of offerings, and livestock should be used to hold them. If there were no oxen, sheep and pigs could be substituted. The commander-in-chief offered the sacrifice in full military uniform, and the generals and colonels accompanied him. The blood of the slaughtered animals should still be "provocative drum".
