Spiritual Kung Fu () (Quan Jing) is a 1978 Hong Kong action martial arts film directed and produced by Lo Wei, and starring Jackie Chan and James Tien. The film also features Yuen Biao as one of the Master of the Five Fists martial arts. Chan was also the film's stunt co-ordinator. It was also known in some other dubbed language releases as Karate Ghostbuster. Plot synopsis Yi-Lang (Jackie Chan) is a smart-alec martial arts student at a Shaolin Temple. An anonymous thief steals a book from the library which teaches a potentially fatal style of Kung Fu. Yi-Lang, along with a group of five other monks, is punished for not stopping the thief, but his bravery leads to him signing up to defend a supposedly haunted portion of the school. Upon discovering the ghosts, who are masters of a supposedly lost style of fighting known as The "Five Style Fists", Yi-Lang offers himself as a student, masters the form and uses it to progress quickly through the ranks of the school. In order to defend the school against the very thief who stole the book from its library, Yi-Lang demonstrates his new style and defeats the invading troupe, with a little help from his five spiritual masters.

As Lo Wei's studio was running out of money, they shelved both films due to cost-cutting measures and Chan was loaned out to Seasonal Films for a two-picture deal. Whilst there he made Snake in the Eagle's Shadow and Drunken Master with Yuen Woo-ping. The success of these two films at the domestic box office prompted Lo to give belated releases to Spiritual Kung Fu (late 1978) and Dragon Fist (1979). Spiritual Kung Fu was Lo Wei's response to Chan's earlier attempt at blending comedy with kung fu in the film Half a Loaf of Kung Fu. The supernatural elements of the film were brought to life by some early examples of Hong Kong special effects. Much of the scripted comedy in the film centred on Chan's exaggerated facial expressions and reactions to his ghostly teachers.
