72 ga cho hak

Kung (played by Eric Tsang) and Kin (portrayed by Jacky Cheung) have been rivals since the 1970s, when they both vied for the affection of the same woman, who ultimately married Kung (Anita Yuen). Today, they own competing phone shops directly across from one another on the busiest street in Mongkok, constantly devising outrageous promotions to outshine each other. In this fiercely competitive environment, fraternizing with the opposition is unheard of—until their children unexpectedly fall in love. The situation becomes even more chaotic when the landlord decides to triple the rent for all the shopkeepers, aiming to evict them for redevelopment purposes.
