The Legend of Bayi's Grandpa.

This film tells the story of Hu Guohua, who falls victim to a plot, framed in a rigged gambling scheme that leads to the loss of his family fortune. Despite his wayward behavior, he reaches a low point by desecrating his family's ancestral grave. In a desperate attempt to deceive for money, he even stages the absurd event of marrying a paper bride. At the brink of hopelessness in life, he unexpectedly encounters Sun Guofu, a master in tomb-robbing, who guides him to self-realization. Although fate plays its tricks and eternal love is elusive, Hu Guohua undergoes a profound transformation from a reckless scion to a wandering adventurer in the world of tomb-robbing.
