Extended information:

Zilong is full of courage.

In the Battle of the Han River between the Shu and Wei armies, Zhao Yun single-handedly rescued Huang Zhong, blocked the Han River and defeated Cao's army. He won the Battle of the Han River and laid the foundation for Liu Bei's march to Hanzhong. This is a famous saying praised by Liu Bei to praise Zhao Yun. This sentence not only shows that Zhao Yun is talented and bold, but also reflects Zhao Yun's bravery and fighting ability, which is invincible in the world.

If the heir can assist, he will assist him; if he is not talented, you can become the master of Chengdu.

When Liu Bei was critically ill, he asked Zhuge Liang to say a famous saying. A man is about to die, but his words are also kind. This sentence shows that Liu Bei has the world in his heart, puts national affairs first, regardless of gains and losses; he affirms Zhuge Liang's character and talent; he trusts and respects Zhuge Liang. Of course, some people say that this sentence is Liu Bei's test of Zhuge Liang; everyone is welcome to discuss.

I get Kongming, just like a fish gets water.

This is what Liu Bei said after he visited the thatched cottage three times and asked Zhuge Liang to come out. The idiom ""like a fish in water"" comes from this. Zhuge Liang was resourceful and the greatest nobleman in Liu Bei's life. Before their three visits to the thatched cottage, the Liu Bei brothers had experienced ups and downs, running around here and there, and their future was uncertain. After Zhuge Liang came out of the mountain, Liu Bei's life and career began to change, as if the sun was clear from the clouds, and he was like a fish in water. Zhuge Liang was not only talented and strategic, but also dedicated and loyal to Liu Bei.

After the Battle of Chibi, he helped Liu Bei pacify Jingzhou, capture the two rivers, and establish the Shu Kingdom
