What ancestors should Zheng worship?

Whether it's the original instrument or the whole truth, it should be dedicated to Sanqing. The founder is Zhang Daoling, which is the inheritance of Zhang's route.

One branch of Taoism is given priority to Sanqing and Yusi, while others are dedicated to Doum Yuan Jun. According to the size of its altar, it has its own arrangements, and some are dedicated to Lv Dongbin's ancestors, and so on.

In short, Taoism pays special attention to inheritance, and it is the best way to worship with the inheritance of one's own master.

Good luck, good luck, and I hope you have a good heart and a good building.
