Myoje, which is also called Myosa or Myojeonjesa, is a gravesite rite. Myoje includes various gravesite rites - Seilje or Seilsa refers to the gravesite rite for five or more latest generations that is held once a year, while Jeolsa, for four latest generations that is held on traditional Korean holidays such as Seol, Hansik, Dano, and Chuseok. Today, Myoje also refers to as Sije, Sisa, and Sihyang as a common practice and these terms mean Myoje that is dedicated to five or more generations, while Sasanje is dedicated to four latest generations.

According to the Chu Hsi's Family Rituals , Myoje is held in the first part of March, however, as Confucian scholars of China's Song Dynasty held Myoje also on Hansik (Cold Food Festival: the 105th day after the winter solstice) and the first day of October, Myoje is generally held in March, Hansik, and on October 1. However, as Korean people put emphasis on Myoje from ancient times, Myoje had been also held in ancestor-memorial days from the Goryeo period, and in traditional Korean holidays – Seol, Hansik, Dano, and Chuseok in the Joseon period.

The objects of Myoje written in the Chu Hsi's Family Rituals, were originally four latest generations, but Myoje for five or more generations was held once a year too. Thus, depending on the region, people hold Myoje dedicated for ancestors from the progenitor to their parents at each gravesite in October; Seilsa, Myoje for five or more generations, is held in March or October; and Jeolsa, Myoje for four latest generations, in Seol, Hansik, Dano, and Chuseok. As for Bulcheonwi (The shinwi (memorial tablet) that will not be taken out of a shrine forever), it is enshrined at a shrine, so Charye or Jeolsa could be held instead of Seilsa, and also it can be dedicated together with five or more generations at the time of Myoje in October.

In Dongguk sesigi (A Record of Seasonal Customs in Korea, by Hong Seok-mo, in 1849?), Jeolsa was defined as a memorial ceremony in which the attendants go to the ancestral graves to hold the ceremony usually in the four major traditional Korean holidays – Seol, Hansik, Dano, and Chuseok. On the day, the ceremony offers drink and food such as liquor, fruits, dried meat or fish, sikhye (sweet rice drink), tteok (rice cakes), noodles, soup, and skewered meat. In general during Hansik and Chuseok, the memorial table is arranged with the largest number of dishes, although it depends on the household. Going to gravesites to hold a memorial ceremony in traditional holidays is Korean custom, and the ancient Korean government added Dongji (winter solstice), making it as the five Jeolsa.

Sije (seasonal rites) is originally held in February, May, August, and October by taking the ancestral tablets of four latest generations out of the shrine to Daecheong (main floored room) of Anchae (Women’s quarters) or Sarangchae (Men’s quarters). It was regarded as the most important ancestral service in Chu Hsi’s Family Rituals. However, since ancient times, Korean people have held Myoje in traditional holidays – Seol, Hansik, Dano, and Chuseok, so ancestral services have been performed more at gravesites than in the shrine. Thus, as a compromise plan, Charye dedicated for four generations has been held in the shrine in Seol, Dano, Chuseok and Dongji; Myoje for five or more generations, around October; and Sije for five or more generations, at gravesites. As there was no detailed explanation in Chu Hsi’s Family Rituals, and its Jesa method was based on Chinese lifestyle, Korean people interpreted into our own way, and certain ritual procedures were slightly changed depending on the household situation. Based on Sarye pyeollam (Easy Manual of the Four Rites, by Yi Jae[1680-1746, civil servant of Joseon]), the Myoje procedure is as follows;

Myoje is generally held at gravesites, but when it rains, it is performed as Mangje (a memorial service by looking out on an ancestor’s grave) with the paper tablet in the joint at Jaesil (a building for holding a memorial service next to a grave or shrine).
