Basic story: I remember seeing this movie in the early 2000's. There are these two brothers training in a temple until their master lets them go to the city. Once they get to the city they try to make some money with bets and catch the attention of guards.
Later the brothers argue and fight each other to the death.
Some other scenes: In the temple while cleaning, they swing a wet towel at each other, which is shown later when they fight when they use swords on each other. Also in the temple, while sitting on a table they fight each other with kicks and then break the table.
