Zhang Ren, a famous general in Shu, is a tragic hero who is difficult to sing with a lone palm, and can he be compared to the Five Tiger Generals in Liu Bei's camp

If the people in the two counties of Brazil and Zitong, which must pass through Liu Bei's army to the south, move all the things that may become Liu Bei's military assets, burn them, build walls and clear the wilderness, and then dig deep ditches in high fortifications, and the defenders of all cities will not be able to hold out, and fight a war of attrition with him, they will not be supplied, so that within a few months, they will retreat, and at that time we will send troops to fight them, and we will definitely win.

At the beginning, when the Wei monarchs heard that Liu Bei had attacked Shu, there were many opinions, and Zhao Jian said: Liu Beizhi is very talented, clumsy in using troops, defeated in every battle, and there is no time to die, how can he still have the ability to conquer others, liu Bei is difficult to achieve this? Although the land of Shu was small and narrow, the four sides were dangerous, and Liu Bei was going to fail. Fu Gan retorted: Liu Bei is benevolent and generous, can win the service of people, Zhuge Liangtong Ancient Bo is resourceful, he has assisted Liu Bei, plus Guan Yu Zhang Fei is loyal, and ten thousand people are difficult to oppose, this is the world's masterpiece, with Liu Bei's strategy, plus these people's assistance, how can we conclude that they can't do anything, I don't think so. Zhao Jian was strong enough to resist Dong Zhuo's obscenity, was mighty and unyielding, had a long reputation, and was deeply respected by Liu Biao and Cao Cao, and he may have said that it was just a political necessity.

After Liu Bei seduced Yang Pei gaohuai, he sent Huang Zhongzhuo as the vanguard, first from Yemeng Pass to the south, and then led most of his men and horses to meet with Huang Zhongjun at Fuxian County, and liu Zhang's troops rejected Liu Xuan, Leng Bao, Zhang Ren, and Deng Xian from Fu County. Liu Zhang, hearing that Liu Bei had brand-new Yang Huai gaopei, and that the army had gone all the way south to FuXian County, was very panicked, at which time his adviser Zheng Du gave Liu Zhang's advice: Liu Bei's army is attacking with great momentum, but they are fighting in our territory, and the white water army that has been recruited may not be willing to have a heart with him; and they are not heavy enough, the grain and grass are not good, and they rely on the autumn wind to supply grain and grass, if the people in the two counties of Brazil and Zitong, which Liu Beijun must pass through to the south, move to the west of Fushui, take away all the things that may become Liu Bei's military assets, and burn them if they cannot be taken away. The walls were cleared, and then the high fortifications were dug deep trenches, and the defenders of each city could not hold out, and fought a war of attrition with him, they had no supplies, so that in a few months, they would retreat, and at that time we would send troops to fight them, and we would definitely win. Zheng Du's plan was right in Liu Bei's weakness, and there was an internal report that should be reported to Liu Bei, Liu Bei was greatly worried, and asked Fa Zheng what to do, And Fa Zheng said that the general should not be in a hurry, Liu Zhang would not listen. Sure enough, Liu Zhang listened to Zheng Du's suggestion and said: I have only heard of rejecting the enemy in order to protect the people, and I have not heard of driving the people away from the enemy. He then disobeyed Zheng Du and deposed Zheng Du, causing the Yizhou defenders to engage Liu Bei. So Liu Bei broke Liu Zhang's army in Fu County. Zhang Ren and Liu Xuan retreated to Luocheng in defeat, and Liu Zhang's son Liu Xunsi defended Luocheng, and the rest of the men and horses retreated to Mianzhu, Liu Zhang sent the escort Army Li Yan to Mianzhu to collect people and horses, and supervise the various armies, but li Yan arrived at Mianzhu and led the crowd to surrender to Liu Bei, and the important town north of Chengdu was only Luocheng, and once Luocheng was lost, Chengdu was not protected, so the Defenders of Luocheng were very stubborn under the leadership of Liu Xun, and Liu Bei's army could not attack for a long time. Liu Bei attacked the city with difficulty, the defenders defended The Martyrs, Zhang Ren secretly led a group of men and horses out of the city at night, ambushed at Yanqiao near Luocheng, planning to sneak up on Liu Bei's army, but did not expect to be recognized by Liu Bei, Zhang Ren fought unyieldingly, and was eventually captured. Liu Bei knew that Zhang Ren was loyal and resolute, and he was well known in Shu, and if he could be persuaded to surrender, it would be a heavy blow to the morale of the Shu army, so he personally persuaded Zhang Ren to surrender, but Zhang Ren shouted to Liu Bei: The old minister will not return to the second lord in the end. Although Liu Bei was not willing to give up, he could only turn Zhang Ren to the head.
