The three main groups of people in Yinyang Road 4 are all intertwined with stories about things. They all flew from Hong Kong to the Philippines on the same flight. Among them, three people, including Lei Yuyang, are cowards trying to buy sex in a foreign land, but they really met a ghost. Hong Tianming is an employee of a courier company. He was sent to send the ashes back to the girl's house, but he met a romantic ghost love. Louis Koo and Sun Jiajun, a young couple who went to the Philippines for a holiday, had a tragedy because they doubted their spouses' love. The style of the whole film is not uniform. The first paragraph is more gimmicky, but the last two paragraphs are not bad.
At the end of Yin and Yang Road 4, the origin of ghosts in Yin and Yang is explained a little, and other characters come back to the tour group one after another and finish the whole thing. The final frozen picture is that when Huang Baiming heard that the plane that just left the airport was going back to Manila International Airport, he couldn't help laughing with a bitter gourd face. This scene completely exposed the positioning of this film, which is a comedy.
