After Au Yiu Cho and Tang Lai Kuen divorced, they each operated Yue De Ju in China and Hong Kong. They lived in peace for many years until the 25th anniversary of the return of the Hong Kong Special Administrative Region. Lai Kuen decided to return to Hong Kong to open a branch and even went to court with Au Yiu Cho to compete for the Yue De Ju brand. The youngest son, Ka Kin, participated in the Greater Bay Area Entrepreneurship Competition and met his elder brother, Ka Him, who served as a mentor. The brothers were separated for a long time and went in opposite directions, so friction was inevitable, but blood is thicker than water. After deepening their understanding of each other, they rebuilt their deep family ties and worked together to develop high-tech virtual technology, allowing their parents to re-experience the ups and downs of the past 25 years. They realized that they had always cared about each other. The two of them cleared up their past grudges and the family of four was finally reunited.
