He saw that Kiyoko and a number of skateboarding teenagers were cutting left and right in the street, and after a long chase, Kiyoko disappeared. Huixiang thought of holding a birthday party for Meng Bo after Meng Bo's house, but did not want to push the door to find that there were already seven beautiful women looking forward to crossing the autumn water. in a fit of anger, Huixiang threatened to advance her honeymoon with her cousin Bigfoot (Shan Liwen) on the gambling boat "Fugui". Meng Bo rushed to the dock to explain to Huixiang that he did not want to find him. At this time, the "Fugui" was about to set sail, and Meng Bo got on board among the tourists. Qingzi and Hong Kong policeman Yazi (Qiu Shuzhen), disguised as a sexy girl, were also on the boat. There is a show for three women, not to mention the aggressive and lecherous Meng Bo.
