Чжу Си
Chinese philosopher, Zhu Xi's book, "The Family Rituals of Zhu Xi" regulated domestic rituals such as weddings, births, funerals and memorial services. Even though it was accustomed with Chinese culture, it wasn't so for the Joseon society. Yi Jae (李栽, 1680~1746) wrote "Sarye pyeollam" ("Easy Manual of the Four Rites") to supplement The Family Rituals of Zhu Xi. Domestic ceremonies, including "jangnye", were always performed according to this book.
