How did everyone know that Zhuge Liang was not as bombastic as Zhao Kuo and Ma Di before he came out and made great achievements?

First of all, before he came out of the mountain, everyone didn’t know what he was like.

But (please look at the following points)

1. Mr. Shui Jing once said, "A crouching dragon and a phoenix can bring peace to the world." Who is Mr. Shui Jing? Half immortal.

2. When Xu Shu left Liu Bei, he also strongly recommended Zhuge Liang to Liu Bei. It can be seen that Zhuge Liang is by no means simple.

3. More importantly, Liu Bei was stationed in the small town of Xinye. He had just lost Xu Shu and had no counselors available. Cao Cao was eyeing him. If Liu Bei wants to overcome the difficulties and accomplish something, it is urgent to get a counselor.

So Zhuge Liang stirred in Liu Bei's heart like a tide. This prompted three visits to the thatched cottage.

After the above points, there should be no doubts from Liu Bei's three people or even all Liu Bei's men. Moreover, as soon as Zhuge Liang came out of the mountain, there was a battle to burn Bowangpo. Dispelling all doubts, it is well deserved.
