First of all, historical facts, which can be proved by examples, are the key moments when the flow of history has changed greatly. The orthodox answer is: Liu Bei cares about the cottage.
First, he is a heroic and heroic talent, eager to be virtuous and polite to corporal;
Second, he can't help it. He has been running around for half his life and changed his master several times, but no one plans for him. If there is no hero's soul, he will go with the flow even if he loses many battles. It can be said that Kong Ming should be Liu Bei's last chance to rise. If we wait a few years, Cao Cao will go south to Jingzhou, and Sun Wu and Liu Bei will be powerless to return to heaven.
Look at Zhuge and Liu Bei's personal ability, which can be seen from his carefulness and personal charm.
In addition, although he was only 27 years old when he was young, the world trend has basically become. Cao Cao dominated the north, Sun Wu divided the east, and Liu Biao was dying. Woe to Shu, chaos to the West. If we let him farm in Nanyang for a few more years, there will be no stage for him in the world, and then we can see his ambition. Although it is called helping Korea, it is more important than making contributions.

Historical background
The yellow turban insurrectionary uprising at the end of Han Dynasty caused great chaos in the world. Cao Cao sat in the imperial court, and Sun Quan recruited troops in Soochow. Liu Bei, the imperial clan of the Han Dynasty, heard from Xu Shu and Si Mahui that Zhuge Liang was very knowledgeable and talented, so he took gifts with Guan Yu and Zhang Fei to Longzhong, Dengxian County, Nanyang County, and asked Zhuge Liang to come out to assist him. It happened that Zhuge Liang went out that day, and Liu Bei had to go home disappointed.
Soon, Liu Bei, Guan Yu and Zhang Fei braved the snowstorm and invited them for the second time. Unexpectedly, Zhuge Liang went out for a walk again. Zhang Fei doesn't want to come again. Seeing that Zhuge Liang was not at home, he urged him to go back. Liu Bei had to leave a letter expressing his admiration for Zhuge Liang and asking him to come out of the mountain to help him save the country's crisis.
After a while, after eating vegetarian food for three days, Liu Bei was ready to invite Zhuge Liang again. Guan Yu said that Zhuge Liang may exist in name only, but he may not have real talent and learning, so there is no need to go. Zhang Fei, on the other hand, advocated that he should make a phone call alone and tie it up with a rope when he didn't come.
Liu Bei scolded Zhang Fei and invited Zhuge Liang for the third time. When they arrived at Zhuge Liang's home, it was already noon and Zhuge Liang was sleeping. Liu Bei dare not disturb him. He stood until Zhuge Liang woke up and sat down to talk to each other.
