Just Another Pandora's Box, also known as Once Upon a Chinese Classic, is a 2010 Hong Kong parody film directed by Jeffrey Lau, starring Ronald Cheng, Gigi Leung, Betty Sun, Eric Tsang, Huang Bo, Guo Degang, Gillian Chung, and Patrick Tam.

In addition to A Chinese Odyssey, the film spoofs Red Cliff and also makes references to other films such as The Eagle Shooting Heroes, Kung Fu Hustle, House of Flying Daggers, CJ7, Kung Fu Panda, Titanic, King Kong, The Green Hornet, and The Matrix, as well as events such as the 2008 Summer Olympics.

Qingyise and Rose Fairy run into Grandpa Buddha and his assistant, who are chasing Bull King for the Pandora's Box.

By accident, Qingyise recites "Prajñāpāramitā" and activates the box, causing him to be transported back in time to the Eastern Han dynasty.

Unable to return to his own time, Qingyise is forced to cooperate with Rose Fairy, who has infiltrated Liu Bei's camp in disguise as an ambassador from Turkestan.
