The Winter Melon Tale.

Fan Tung (Liu Kai Chi) is one of the four deities under the Stove God. He has offended the Queen Mother of the West of being ravenous and gets imprisoned for 500 years in the winter melon. By chance Tin Dai Kwai (Sunny Chan) and his wife Chung Bik Yuk (Louisa So) free him from constraint. Tung gets flattened by Kwai's older brother Tin Tai Fu (also played by Liu Kai Chi) accidentally and his spirit enters Fu's body inexplicably while losing all his instincts. Tung starts living in Kwai's house and getting closer to the family. Yuk finds Tung suspicious and she tries to unmask him by all means. Having failed in his attempt to return to Heaven, Tung becomes reliant on the help of six little deities who assimilated his instincts released from the melon, and since then Tung is aware of the fickleness of human nature.
