At that tail of the warhead, the drag armour-piercing firebomb is filled with a drag agent and a fireagent, Under the pressure of propellant propelling warhead, it will spontaneously ignite to produce open flame, So it can break through the oil drum and ignite or detonate the gasoline. However, the old-fashioned traced armour-piercing firebombs have obvious trajectories due to traced light when they are launched. Therefore, it is very easy to expose oneself while pointing targets to friendly forces. Therefore, the new tracer armour-piercing firebombs now equipped all start to burn and emit light only after the projectile flies out of the muzzle for a certain distance (the generally set safe distance is 100 meters, which makes it impossible for the enemy to judge the firing position with tracer ammunition, while targets within 100 meters do not need to be indicated by tracer), The principle is generally to ignite the tracer and combustion agent carried by the projectile by accumulating the heat generated by the warhead's friction with the air after flying for a certain distance to a certain extent.城乡结合部刘家村的土地被高速发展的城市占用，德昌(李琦)老汉一家人变成了“城市人”，城市人分房子按工龄、级别，可他们分房子怎么论？本来德昌老汉家分到了18层，可18层不是说是地狱嘛，因此，德昌老汉宁愿住在最高层，以便求得“把别人都踩在脚下”的心理平衡。突然农村变成城市，传统观念与现代意识，小农意识与商品时代的冲突，让他们的爱情、婚姻、择业面临着越来越多的矛盾，德昌老汉与誓要彻底成为城市人的二儿媳妇(黑妹饰)、思想解放的三儿子(孙涛饰)等与周围的人演绎了许多的悲欢离合，最后他们在竞争中以朴素的品质和坚韧的性格承受挫折，精明地审时度势，最终融入了城市。2.
