In 1947, lao Chiang launched the Lunan Campaign in an attempt to annihilate the main force of our army's eastern field army, when Chen Cheng, as chief of staff, divided his army of 240,000 people into three roads and launched an attack along the river in order to obtain a greater victory rate. However, our army saw the tricks and dismantled the moves, and broke through their way of fighting one by one. After that, Chen Cheng asked the whole army to unite closely and sent Wang Yaowu's three armies to assist in the battle, trying to encircle our army, but in the end it was also defeated.

Wang Yaowu actually did not want to carry out Chen Cheng's instruction to let him assist in the battle, because he himself was not rich in troops, and then sent 3 armies to support Chen Cheng, his remaining troops were even less, and the battle situation was unknown. If at this time our army takes advantage of the void to attack them, they will have no power to fight back and can only become a thing in the pool.
Chen Cheng, on the other hand, believed that he was safe to win, but his strength was not good, if Wang Yaowu could send 3 companies of troops to assist, then it would be a big deal to win this battle, so under his compulsory orders, Wang Yaowu had to obey the dispatch.
The army led by Chen Cheng has a great advantage over our army in terms of numbers. Such a huge team, compact in structure, advanced rapidly. Our army originally planned to take advantage of the enemy's lack of preparation to break through and disperse them, but later found it difficult to do so.
According to the situation at that time, if our army wanted to attack the army led by Chen Cheng in the south, the success rate was not high; if it wanted to attack the troops led by Li Xianzhou in the northern dipping area, it was more promising, because Li Xianzhou's army was slowly advancing in the shape of a long snake, and although it was numerous, it was not dense enough for the proofreaders. Our army took the opportunity to quickly move north and surrounded Li Xianzhou's three armies, and in order to prevent Chen Cheng from coming to support Li Xianzhou, our army confronted Chen Cheng and diverted Chen Cheng's attention. Li Xianzhou's troops, on the other hand, were being beaten by the troops led by General Su Yu of our side.
However, the frontal engagement between our army and Chen Cheng's troops in the south, because our side was small in number and outnumbered, was gained by Chen Cheng's army, which made the enemy mistakenly think that they had won a victory. Chen Cheng thought that the main force of our army had been annihilated, so he ordered Li Xianzhou and others to quickly come and clear the battlefield.
Although Li Xianzhou's troops are surrounded by our army, they are numerous in number, and if they are determined to break through, there is a great chance that they will succeed, and even if our army successfully surrounds them, they will never dare to slacken off in the slightest, and if they gather the strength of the three armies and make a single effort, it is very likely that they will successfully break through.
Li Xianzhou ordered the encircled 46th Army to take the lead in breaking through, because the 46th Army was more weaponized and equipped, and the soldiers were relatively brave.
Han Liancheng, commander of the 46th Army, refused to break through immediately because his troops lacked supplies and needed time to unite, so he asked his troops to delay the breakthrough by a day.
It was precisely because of this "wrong" decision that Su Yu led his army to take advantage of this opportunity to annihilate this army in one fell swoop. About 60,000 soldiers were completely annihilated.
And why didn't Han Liancheng follow the order of the leader Li Xianzhou to break through immediately, but delay it?
Han Liancheng, a native of Guyuan, Ningxia, a former senior general of the Kuomintang army, was one of the four legendary generals of our party who went deep into the Dragon Pond Tiger's Den, and was a member of our army.
Han Liancheng devoted his life to the party, and in 1955, he was awarded the rank of lieutenant general.
