Do you know a Chinese Movie called "Red Cliff"

Tweet

The Movie is based actual fact in ancient Chinese historic three kingdom period (184 A.D.-280 A.D.). A period of sword and blood, of hero and plots. However, I have different idea about some settings. For example, a general shouted:"form up" but his soldiers just rush to the enemy without any formation. Did not he said "form up"? I wonder. When the riders chasing the other side, they confronter shield wall and spears, the general did not give order to charge at all cost, Why? I thought this is only way to break their foe's formation and drive them to the hell. I thought there will be Chinese style palanx but I did not see anything. Did see any? And the last one. If the army of that Chinese period encounters Roman legions what will be the result? I wonder....
