It's a Mad, Mad, Mad World III

The Biu Family collects their lottery winnings in Canada and returns to Hong Kong to start a new life together, minus the second daughter due to a family quarrel of her involvement with her boyfriend. After Mrs. Biu shows off her money to her old friends at her bank, she loses it all in a robbery. Now, void of their new found wealth, the Biu Family must start over from scratch again.
