Chao Gai, nicknamed "Pagoda-Shifting Heavenly King", is a fictional character in Water Margin, one of the Four Great Classical Novels of Chinese literature.

Chao Gai earned his nickname "Pagoda-Shifting Heavenly King" after carrying a pagoda miniature from the west side of a creek to the east, where his village stood, to deter malevolent spirits.

Apart from having a wide network of friends and acquaintances throughout the jianghu, he also maintains close friendships with the local chief constables Zhu Tong and Lei Heng.

While Lei Heng is enjoying the village's hospitality, Chao Gai surreptitiously meets Liu Tang and finds out what happened.

In the meantime, the local magistrate assigns Zhu Tong and Lei Heng to lead soldiers to arrest Chao Gai and his friends.

Wang Lun, the outlaw chief, feels that Chao Gai and his friends pose a threat to him so he tries to send them away with gifts and excuses.

For the most part, he lets Song Jiang lead Liangshan forces into battle while he remains behind to guard their base and provide reinforcements.
