In the late Western Han Dynasty, the Confucianism motivated reformation of the national worship system largely influenced the Taishan Mountain worship. After the reformation, there emerged two different worship systems: one located in the capital area and the other located in the Taishan Mountain area. Worshiping the god of Taishan in the capital area is the national worship which follows the structure of 坛祭木主(a ritual to honor ancestral tablets that are made out of wood). This worship means that Confucianism deifies the god of Taishan as the god of nature. For many generations of kingdoms, the Taishan Mountain worship has been following the same structure. The reformation constantly influenced the worship in the Taishan Mountain area as well. Because Confucianism rituals was integrated with folk religion, from the late Western Han Dynasty to Tang Dyansty, the worship in this region appears to be very complicated with the combination of 坛祭(rituals conducted in altars) and 庙祭(rituals conducted in front of the graves of ancestors). It was the Northern Song Dynasty when it was finally developed to be simpler as the influence of the folk religion grew greater. The structure of the worship in the Taishan Mountain area gradually became rather traditional and folk religious than national as it was no longer influenced by the Confucianism rituals.
