I forgot movie name.. can anyone help me? please?

i saw a movie an tv .. it was achinese .. i guess it must be shot in 60s or 70 s without any CG work.. but must be big budget project.. and the story line was much similar to gladiator.. a king kinda overruling a country and then 2 heros who were brought up in the same place but finally ending up in two different sides in war because of sitations and the climax was the fight between two heros.. can any one help me out ? i remember hearing a word like "chunkistan" very often in the movie
