This paper’s aim are to pursue what was the short-term mourning’ system(短喪制) and the way of two track operations for posthumous emperor of Song dynasty, which are typical characters in performing funeral ceremonies. For the characters of short-term mourning’ system, we need to trace it from Han dynasty having started the original of the system, and all the way to the Tang dynasty including Wei-Jin Nanbeichao periods, and for the way of two track operation, Song’s contents and characters have to be compared with those of Tang’s. After analyses, I have found out that the short-term mourning’ system and third-year memorial service of funeral ceremonies for Song emperor were being conducted at the same time with the separated form from each other between the royal families and officials, and also could confirmed that Song’s funeral ceremonies were results affected and integrated from the factors of Chinese previous dynasties.
