When Liu Bei saw Ge Liang for the first time 1 time, he praised him as a rookie and knew three points in the world. This shows that Zhuge Liang has thoroughly studied the current situation of the world. If he were just a farmer through and through, he would never have such knowledge. Therefore, as far as sources are concerned, Zhuge Liang is not worse than Liu Bei, and even obtained some first-hand information through Zhu Gejin. Of course, Zhu Gejin didn't betray him, and Soochow didn't say much, but Zhuge Liang was born with talent.
Although Zhuge Liang is a farmer, he doesn't often stay here, because he has to have a rest even when he is working. Later Zhuge Liang visited the thatched cottage, and Zhuge Liang went out to avoid it. At that time, it seemed unreasonable, but Zhuge Liang often went out to visit friends and discussed the world situation with those friends. Even Mr. Shui Jing said that Zhuge Liang was very talented, which showed that Zhuge Liang was not a thorough farmer.
Zhuge Liang didn't want to waste his talents, so he was expecting an opportunity, and here Xu Shu was an opportunity, because he met Zhuge Liang first, and Liu Bei introduced Zhuge Liang when he left, which made Zhuge Liang soar, but the opportunity was for those who were prepared. If Zhuge Liang is willing to be a farmer, there will be no future achievements.
