The sword is not old, which means that although it is old, it is not less powerful than it was back then, which generally refers to being old or out of the industry for a long time, but the skills and skills have not decreased. The idiom comes from the seventieth chapter of "Romance of the Three Kingdoms", "Zhong angrily said: 'The concubine bullies me to be old, but the sword in my hand is not old!'"
According to the "Romance of the Three Kingdoms", after Cao Cao defeated Zhang Lu to capture Hanzhong and eastern Sichuan, in order to fight for Hanzhong, Liu Bei adopted Zhuge Liang's suggestion to return the three counties of Jiangxia, Changsha and Guiyang in Jingzhou to Eastern Wu, and sent Yi to Eastern Wu, successfully persuaded Sun Quan to attack Hefei to contain Cao's army, and then sent Zhang Fei and Ma Chao to capture Hanzhong.
After Cao Cao received the news that Zhang Fei and Ma Chaotun had sent 50,000 troops to reinforce Xiahou Yuan and Zhang He to resist the Shu army stationed in Dongchuan. After Cao Hong led his troops to Hanzhong, he ordered Zhang He and Xiahou Yuan to take advantage of their own dangers, and he personally led his troops to resist the enemy. On the Shu Han side, Zhang Fei and Lei Tong were stationed in Brazil, while Ma Chao took Wu Lan as the vanguard and encountered Cao Hong. Cao Hong's array cut off the teeth of Ren Kui, and after Wu Lan's defeat and reunited with Ma Chao, he couldn't distinguish it from the insistence.
Cao Hong saw that Ma Chao had not been out for days, worried that there was a conspiracy, and led his troops back to Nanzheng. Zhang He thought that Cao Hong was too cautious, so he asked Cao Hong for his life, asking to lead his troops and horses to attack Brazil, and said wildly, "Everyone is afraid of Zhang Fei, I regard him as a child's ear! I will capture him if I go here!" and even did not hesitate to make a military order.
As the so-called arrogant soldiers will be defeated, Zhang He led the headquarters of 30,000 soldiers and horses to go out, but in the battle with Zhang Fei, it was repeatedly defeated, not only failed to capture Brazil, but even the passes where they were stationed were lost one after another, after the defeat of Wakou Pass, Zhang He's headquarters lost all the soldiers and horses, and waited until Zhang He panicked to get rid of the pursuers, and there were only more than ten people left around him.
After Zhang He returned to Nanzheng, Cao Hong originally wanted to kill Zhang He, but fortunately Guo Huai and others advised him, so he agreed to let Zhang He make meritorious service and ordered him to lead 5,000 troops to attack Pujia Pass. Zhang He led his troops to Pujia Pass, defeated the defender Meng Da, and another guard, Huo Jun, hurriedly sent someone to inform Liu Bei of the news and asked for reinforcements.
Zhuge Liang thinks that now Zhang Feitun's soldiers are at Wakou Pass, which is also a critical place, and cannot be left lightly, so he decided to choose another person to meet Zhang He, and the veteran Huang Zhong took the initiative to ask for help, Zhuge Liang was worried about his old age, but Huang Zhong took off the big knife on the shelf, rotated like flying, and took off the hard bow on the wall, and dragged two pieces in succession, so as to prove that he was enough to fight. Zhuge Liang asked him who could be the deputy general, and Huang Zhong recommended the veteran Yan Yan, and Liu Bei sent the two to fight.
Huang Zhong and Yan Yan arrived at Pujia Pass, Meng Da and Huo Jun saw that the reinforcements were two veterans, and they were quite contemptuous. For this reason, Huang Zhong led his troops down to the pass and fought against Zhang He, Zhang He saw that the Shu army sent a veteran, and said with a smile, "You are so old, you are still shameless, and you still want to fight?"
When Huang Zhong heard this, he said angrily, "The vertical son deceives me into being old, but the treasure knife in my hand is not old!" Then he immediately stepped forward to fight with Zhang He, the two fought for more than 20 years, Yan Yan outflanked Zhang He from the small road, and under the attack of the two armies, Zhang He was defeated, and retreated for eighty or ninety miles overnight.
Cao Hong learned that Zhang He had been defeated again, and wanted to punish him, but Guo Huai thought that if the persecution was too much, Zhang He might surrender to Shu Han, and suggested sending generals to rescue and monitor. Cao Hong then sent Xiahou Shang and Han Hao to lead 5,000 troops to help the battle, and the two sides fought again, but Huang Zhong was defeated and retreated one after another, and he retreated to Pujia Pass and held out. Seeing that Huang Zhong had not been out for a day, the Wei army was slightly slack, so Huang Zhong attacked the camp at night, and Xiahou Shang and Han Hao were defeated and fled.
Zhang He was originally in the rear, and before he could fight, he was rushed by the defeated army of Xiahou Shang and Han Hao, and he could not organize the army to meet the battle, so he had no choice but to give up Zhaizha and defeat all the way, and finally defected to Xiahoude in Tiandang Mountain. Huang Zhong then killed, Zhang He suggested to hold on, but Han Hao was unwilling to fail, and borrowed 3,000 troops from Xiahoude to meet the battle again, but was cut down by Huang Zhong with a knife, and the Shu army took advantage of the situation to attack the mountain.
Seeing this, Zhang He and Xiahou Shang hurriedly led the army to meet the battle, and suddenly there was a fire behind the mountain, and Xiahou De raised troops to put out the fire, but he didn't want to be the veteran Yan Yan in the back mountain, and as a result, Xiahou De was killed by Yan Yan. Zhang He and Xiahou Shang could only give up Tiandang Mountain and go to Dingjun Mountain to join Xiahou Yuan in the case of being flanked between the front and back.
After Huang Zhong and Yan Yan captured Tiandang Mountain, they sent people to Liu Bei to report their victory, and Fa Zheng suggested that Liu Bei could raise troops to the north and take advantage of the victory to capture Hanzhong. Liu Bei then ordered Zhao Yun and Zhang Fei to be the vanguards, and he and Zhuge Liang led 100,000 troops to the north, set up camp in Pujia Pass, and rewarded Huang Zhong and Yan Yan for their previous meritorious service.
Liu Bei thought that Dingjun Mountain was the key to capturing Hanzhong, and asked Huang Zhong if he dared to take Dingjun Mountain again, Huang Zhong agreed angrily, and then led the veteran Huang Zhong to kill Xiahou Yuan in the Dingjun Mountain Formation, which made great contributions to Liu Bei's capture of Hanzhong.
