In the 1970s, young sworn brothers Shi Jian and Harbin Institute of Technology became bitter rivals because of their deep love for George W. Tao Hong. Until 20 10, Sai Yeung Choi Street in Mongkok, Hong Kong was a place where merchants competed for tourists. Ironically, all merchants tried their best to compete for tourists. However, under the jittery situation that the big owners are forced to move by increasing rents, they are inspired by the belief that "everyone is for me and I am for everyone". The triangular relationship between Shi Jian, Hargong and Tao Hong Jr., the love between the next generation of the two families: the ideal otaku Hazai and the trendy and lively Mei Jian, and the kungfu girl Hanu and the tired and lazy Jianzai should also end at the same time.
