Luo is a drama in the Yuan Dynasty, which tells the story of an evil servant who cheated his superiors and subordinates, stole his wife, cheated his young master, and told his master Luo that his young master was dead and stole furniture. Such a servant is a wolf. Accepting such people as subordinates is "inviting wolves into the room."

? In the history of the world, events that lead wolves into the room abound.

In the 4th century AD, the Huns moved eastward and arrived in Eastern Europe. The Roman emperor Wallis, the "eternal city", accepted Gothic refugees, and the influx of barbarians opened the curtain of a century of decline. The Goths couldn't stand the slavery of the Romans and launched the battle of the Adriatic fortress. Two-thirds of the Roman legions were annihilated, Wallis was seriously injured, and the besieged Goths died in the fire. As the Goth soldiers pointed out, there are rubble everywhere, and civilization has been looted by barbarians, which is a retrogression in human history.

With the decline of Rome, after the Roman Legion was forced to leave Britain in the 5th century, in order to resist the invasion of Scots and spears, the Celts took the initiative to invite Jutes to station troops, and then the three Germanic tribes of Jutes, Angles and Saxons invaded on a large scale, and almost all Celtic adult men were burned to death.

Looking back at the history of China, we can see that inviting wolves into the house is too numerous to mention, among which the three countries are the most important.

At the end of Emperor Heng, Dong Zhuo held heavy power and occupied the capital. In order to fight against Dong Zhuo, Yizhou Muhanfu voluntarily gave up Yizhou when Yuan Shao was green and yellow. Then, Dong Zhuo killed Yuan Shi, and heroes all over the world embraced Yuan Shao. Han Fu dared not go to see Zhang Miao, the satrap, and Yuan Shao sent messengers to discuss something important with Zhang Miao. Han Fu was surprised by this and finally committed suicide in fear.

The same is to give way, but Liu Zhang is more shameful than Hanfu. After Liu Zhang inherited the Yizhou secretariat, he was at odds with his father Zhang Lu, which coincided with the rumor that Cao Cao wanted to crusade against Zhang Lu. Liu Zhang chose to invite Liu Bei to Sichuan, divide the grain among the soldiers, and let Liu Bei attack Zhang Lu, but Liu Bei chose to recuperate and bite the hand that feeds him. The following year, Sun Quan turned to Liu Bei for help. Liu Bei used this as an excuse to ask Liu Zhang for ten thousand horses. Liu Zhang refused and only promised 4 thousand. Their relationship broke down, and Liu Bei took the opportunity to kill Yang Huai, the overseer, capture Yizhou and confront Liu Zhang. Finally, Liu Zhang surrendered to Liu Bei, and at this point, the world scored three points.

Not only Liu Bei was a wolf who entered the house, but also Cao Cao and Lu Bu were unwilling to lag behind. Zhang Xiu led Cao Cao into Wancheng and nearly died; Dong Zhuo hired Lu Bu and died; Liu Bei saved Lu Bu, was occupied by pigeons and birds, and lost Pi; Sun Quan lent Jingzhou to Liu Bei, but if he borrowed it, he would lose his wife and soldiers. The last laugh was Sima's usurpation of Wei for Jin.

Wei and Jin dynasties were more chaotic, and the chaos of eight kings led to five chaos. In the prosperous Tang Dynasty, the conference semifinals had lived together in Chang 'an, and Xuanzong trusted An Lushan, the general of the conference semifinals, which led to the Anshi rebellion and the end of the unparalleled rule of Zhenguan.

Wolves are not to be seduced, but be careful when seducing wolves. For example, Yu Xun once ordered Liu Bei, Lu Bu and Yuan Shu to kill each other and drive the tiger to devour the wolf, taking advantage of the fishermen.
