name of a Chinese dynasty, remains of sacrifice, bury, fall, sag
隋 centers on the idea of something falling or sagging, which extends to burying or the remains left after a sacrifice. The name of the Chinese dynasty is a historical application of the character.
隋 originally depicted meat (月) being cut or falling apart, possibly with a hand or tool, giving the sense of falling or sacrificial remains. The left ⻖ (mound/earth) may have been added later, linking to burying. The exact historical development is uncertain.
The left side ⻖ looks like a mound of earth, and the right side has 月 (meat/flesh) under something like a hand or tool. Picture sacrificial meat falling onto an earthen mound, sagging as it is buried.
For ズイ, imagine a sagging, buried sacrifice that is 'zooey' (like a messy, zoo-like scene): zooey -> ズイ.
