compared his own intelligence to that of the famed Han Dynasty strategist Zhang Liang, and further believed that his own knowledge surpassed that of Zhang. It appeared to be around this time that Cui became a Taoist. Previously, Cui was said to dislike Daode Jing and Zhuangzi, the most important Taoist works, but he particularly despised Buddhism, believing it to be a religion of barbarians. After he met the Taoist monk Kou Qianzhi, who had reorganized the Taoist religious thoughts but received few adherents, he became a follower of Kou, and he made many petitions to Emperor Taiwu endorsing Kou's writings. Emperor Taiwu was impressed and became a Taoist and a follower of Kou as well, giving official approval to Kou's followers' proselytization of Taoism throughout his empire and approving a large amount of stipend for Kou's religious ceremonies. Shandong, Hebei, Henan, Shaanxi, and Shanxi were where the Celestial Masters northern branch operated, while Louguan and Guanzhong Daoism developed around Henan, Shanxi and Shaanxi. Celestial Masters are not believed to be connected with stele founded in Shaanxi. An anti Buddhist plan was concocted by the Celestial Masters under Kou Qianzhi along with Cui Hao under the Taiwu Emperor.

Cui Hao was among the ministers who suggested that he attack Xia, believing that Xia's cruel laws made it the obvious target, and Emperor Taiwu agreed. It was also around this time that Emperor Taiwu considered making the minister Li Shun (李順), who was related to Cui by marriage, a major general. (Cui's younger brother was married to Li's sister, and his nephew was married to Li's daughter.) Cui believed Li to be frivolous and unsuitable and persuaded Emperor Taiwu of that belief. From this point on, Cui and Li became political enemies. In 427, after fighting dangerously but with Cui at his side, Emperor Taiwu captured the Xia capital
