Overview: After graduating from college, Ng Yun Fat joined a real estate company as sales executive. He is a smart young man always looking for opportunities to make money. His girlfriend, Fong Mei Lai, is a pretty girl with a simple mind. After overhearing a conversation between Yun Fat and a client, she decided to buy a flat so they can get married. When Yun Fat found out that one of his clients wanted a flat, he sold the one which Mei Lai bought and made some money. Mei Lai was very angry when she knew about it. Yun Fat's old-fashioned mother and tomboy sister moved to the city from Lamma Island. They sold all their properties on Lamma Island and used the money to buy a flat in the city which Yun Fat considered to be old and shabby. When he was told he has to move in he was totally stunned.
Overview: Ng Yun Fat's mother, although now living in the city, still keeps the habits of country life. One day, Yun Fat's colleagues wanted to visit his new flat and have a house-warming dinner. When they arrived, they realized that Yun Fat's mother is an old-fashioned woman still living with old traditions. They also found her cooking to be very non-hygienic. Due to these psychological effects, they all ended up with diarrhea. Yun Fat's mother, apart from being old-fashioned, is also very careful with her money. She exchanged their old colour television set for a black and white set so they wouldn't have to pay to have it repaired.
