What is Longzhong talking about?

After the battle of Guandu, Liu Bei fled to Jingzhou and defected to Liu Biao. Liu Biao allocated some troops to him to stay in Xinye (now Xinye County, Henan Province). Liu Bei is an ambitious man, because his ambition has not been realized, and his heart is always unhappy. He wants to find a good assistant. He found a famous man named Si Mahui in Xiangyang, so he went to visit him specially. Si Mahui said, "There are Wolong and Feng Chu in this area. If you can invite one of them, you can calm down the world. " Si Mahui told Liu Bei: Wolong is Zhuge Liang, and the word is Kongming; Feng Chu's name is Pang Tong. Xu Shu is also a local celebrity, because I heard that Liu Bei was recruiting talents, so I came to see him. Liu Bei was so happy that he left Xu Shu as his counselor. Xu Shu said, "I have an old friend, Zhu Gekongming. People call him Wolong. Does the general want to meet him? " After listening to Xu Shu's introduction, Liu Bei said, "Since you know him so well, please come hard and invite him!" Xu Shu shook his head and said, "This can't be done. People like this must be personally invited by the general to show your sincerity. "

Liu Bei successively heard that Si Mahui and Xu Shu attached great importance to Zhuge Liang. Knowing that Zhuge Liang must be a great talent, he took Guan Yu and Zhang Fei to Longzhong to find Zhuge Liang. Zhuge Liang visited the hut and was finally moved by Liu Bei's sincerity and took Liu Bei to his hut. Zhuge Liang saw that Liu Bei was so open-minded and asked for advice, so he had a heart-to-heart talk with Liu Bei. He said: "Now Cao Cao has defeated Yuan Shao, with an army of1100,000, and he is holding the order of the Emperor. We can't compete with him by force alone. Sun Quan has occupied Jiangdong area for three generations. Jiangdong has a dangerous terrain, and now all the people have joined him, and a group of talents are working for him. It seems that we can only unite with him and can't play his mind. "

Then, Zhuge Liang analyzed the situation of Jingzhou and Yizhou (now part of Sichuan, Yunnan, Shaanxi, Gansu, Hubei and Guizhou), and thought that Jingzhou was an important military place, and Liu Biao could not keep this place. Yizhou has a fertile and vast land, which has always been called "the land of abundance", but Liu Zhang, the owner there, is also a weak man, and everyone is dissatisfied with him. Finally, he said, "The general is a descendant of the royal family and is famous all over the world. If we can occupy Jingzhou and Yizhou, unite with Sun Quan and rectify internal affairs, we can March from Jingzhou and Yizhou and attack Cao Cao once we have the opportunity. At that time, who will not welcome the general? In this way, we can achieve great things and restore the Han Dynasty. " After listening to Zhuge Liang's incisive and thorough analysis, Liu Bei's thoughts were suddenly enlightened. He felt that Zhuge Liang's talents were rare, so he earnestly asked Zhuge Liang to come out of the mountain and help him complete the great cause of reviving the Han Dynasty. Zhuge Liang went out to assist Liu Bei. Later, people called it "three visits to the thatched cottage" and called Zhuge Liang's conversation "Longzhong Dui".
