In A.D. 196, Sun Ce sent a water army to attack Guling on the south bank of Qiantang River, but it was unable to attack again and again. Sun Jing made a plan and said, "Wang Lang is very strong in defense and should not attack head-on. There is a road leading to the tea capital, which is dozens of miles away. You can bypass Guling. You give me an army, and I will besiege him from Chad and give him a surprise attack. I will definitely win! " As soon as Sun Ce heard the reason, he sent troops to him as planned. At the same time, the army was ordered to get hundreds of vats full of water, giving people the feeling that they were ready to fight a protracted war. At night, he ordered the army to light more lights to make the enemy think that Sun Ce's main force was still in place. When Sun Jing's army suddenly appeared in Gaoqiantun near Guling, Wang Lang was surprised and quickly sent Zhou Xin to lead the troops. However, Zhou Xin was no match for Sun Ce and soon lost. Zhou Xin died, and soon Guling fell, and Huiji District was occupied by Sun Ce.
It is a strategy to give a quick attack when the other side is psychologically and materially unprepared. Only by keeping a high degree of vigilance in life can we face sudden accidents.
