Taoism has four protectors. There are three different opinions:

First, it refers to the generals Ma, Zhao, Wen and Thursday (Ma,,,, Zhou Guangze), which is the view of the Qing Dynasty.

Secondly, it refers to the four marshals (Yue Fei, Zhao Gongming, Wen Qiong and Kangxi).

The third is a more popular and orthodox view, that is, the true gentleman, the Fu Zhenjun of Tian, the Chu Muslim gentleman of Yi Shengbao, and the true gentleman of You Shengzhen Wu.
