The tradition of bullfighting.
The match lasts 10 minutes for each pitted cow. If in ten minutes there is no cow that ran because of the opponent's horn attack, then the game is declared a draw. If before the end of time given by one of the cows ran due to an opponent's horn attack, then the cow was declared defeated by the jury.
I noted this attraction some time ago to show you the steemian. This is the habit of Aceh cattle farmers at the end of the year to duel their cattle.
