If you are kind enough, please walk alone; if you want to have wisdom, please walk alone; if you want to be yourself, please walk alone. A gentleman is inclusive but does not form cliques, while a petty person forms cliques but is not inclusive. This means that a gentleman unites without collusion, while a petty person colludes without uniting. A gentleman interacts based on righteousness, while a petty person colludes based on interests. Forming cliques is for the weak, seeking power and groups is for the weak, and merging with groups will inevitably lower intelligence, and lowering intelligence will inevitably lead to a rabble.
