Sang-Yeo is a tool carrying a corpse of the deceased and is called as Dae-Yeo or So-Yeo according to its size. The shape of Sang-Yeo is similar to palanquin.
In the case of kings and nobles, they usually burn Sang-Yeo after using it, which is different from common people. Because it took a lot of time and money to make Sang-Yeo, common people prepared it by each village or family, stored in a Sang-Yeo house and shared.
Wooden Sang-Yeo was replaced by flower Sang-Yeo, and has become increasingly difficult to find due to rural to urban migration caused by industrialization in the 1960s and 1970s.
