Besides Sun Quan and Cao Zhen being relatively weaker, others such as Wei Yan, Pan Zhang, and Lyu Meng are all outstanding among their peers. As for Zhuge Liang and Sima Yi, they are basically the strongest among their generation, so even if they have pride, they know to restrain themselves.
Only Sun Quan among these people is weaker in ability and has high self-esteem, looking down on others somewhat. So, after Zhuge Liang informed the group and even invited Sun Quan twice, and Sun Quan didn't oblige, Zhuge Liang calmly stopped notifying him.
Even matters like Zhuge Liang temporarily leading the three armies didn't elicit any opinions from people like Chen Gong and Zhang Liao. Although Zhuge Liang still has many shortcomings, his caution has earned even Chen Gong's admiration.
