一、导语设计 公元前260年,秦国发兵进攻力量强大的赵国,赵国派老将廉颇率军迎战。廉颇在长平筑垒坚守,双方相持三年。在此情况下,秦国使用反间计,故意扬言廉颇只善守而不善攻,秦国不怕廉颇,最害怕的是赵括。赵王没有真正了解廉颇的军事才能,也不去向将士了解战争的情况,征求具体的对策,就信以为真,调回了廉颇,改派缺乏作战经验、只会纸上谈兵的赵括为将。 赵括到阵前,也没有调查研究,盲目率军出击,被秦军包围,粮食供应又被切断。赵军断粮46天,五次突围不成,结果赵括被秦军射死,40万赵军士兵在投降后全部被活埋掉。这就是历史上有名的“长平之战”。赵国惨败的主要原因之一,就是赵王和赵括都没有深入地调查研究。调查研究对于战争是如此重要,对其他工作又何 First, the design of the lead In 260 BC, Qin Guofang made a strong offensive force Zhao Guo, Zhao sent the veteran Lianping led the army to fight. Lianping built its base in Changping, and the two sides held for three years. In this case, Qin used countermeasures to deliberately assert that Lian Po is good but not good. Qin is not afraid of Lambi and most afraid is Zhao Kuo. Zhao Wang did not really understand Lim’s military talents, nor did he go to the soldiers to understand the war situation and solicit specific countermeasures. He believed that they were true, and he returned to Lian Po, and relocated Zhao Kuo, who lacked combat experience and would only talk on paper. Before Zhao Kuo arrived at the battlefield, he did not investigate and study. He blindly led the army to attack and was surrounded by the Qin army. The food supply was cut off again. Zhao Jun broke the grain for 46 days and failed to break through five times. As a result, Zhao Kuo was shot dead by Qin Jun and 400,000 Zhao Jun soldiers were all buried alive after surrendering. This is the history of the famous “Chang-ping war.” One of the main reasons for Zhao’s disastrous defeat was that Zhao Wang and Zhao Kuo did not conduct in-depth investigations and studies. Investigations and studies are so important for wars, and for other jobs
