Since Chao K’uang-yin (Zhao Kuangyin) established the Song Dynasty (960-1279), the Imperial Kinsmen Sacrificial Rites have spread from the Central Plains to Dachikan and Nanmen of Doumen District and neighboring areas over the past thousand years. Zhao Clan people use the rites to pay respect to their ancestors at Chinese New Year and on other major occasions at their family shrines.

Replete with firecrackers, gong and drum, joss sticks and candles, offerings, roast suckling pig, treasure plate burning, altar table, and so on, the rituals have been passed down to the 29th-generation descendants of Zhao Kuangmei in Doumen. Kuangmei was second brother of Zhao Kuangyin.
