祝延平版《武松》通过“景阳冈打虎”、“兄弟话别情”、“斗杀西门庆”、“醉打蒋门神”、“身陷都监府”，“血溅鸳鸯楼”、“二进十字坡”、“二龙山聚义”这个8个小故事，将武松传奇而平凡的一生刻画的淋漓尽致，在他身上我们看到了什么叫“逼”——丑恶的社会在逼迫武松，让他好人做不得，他不得不杀人，当武松只有杀人这一条路可走时，杀人的标准也就不再象以前那么精确，而是模糊了，道德的约束也就随之瓦解了。

"This' knowledge 'is out of ammunition, Before, we used ordinary bullets to hit these big wasps. So the killing efficiency is not high, After hitting them with '74 jets', We found that they were very afraid of fire. So he took out all the tracer armour-piercing bombs that were pressed at the bottom of the box. These bullets have three more functions than ordinary bullets: luminous, armor piercing and burning. This kind of bullet is mainly to use the tracer function to provide target indication for friendly fire.

That's why so many of these munitions are being distributed, But this is not the case, The Vietnamese army did not have the patience to build positions to fight our army.

At that time, they were taken out at the right time. We used the battle gap to replace all the ordinary bullets with traced armour-piercing firebombs to hit the second batch of big wasps. The effect was not good.
