1, the United front is usually limited to the * * * production party, because its definition involves classes, that is, fighting for the same interests and overthrowing hostile classes. This kind of thing is not suitable for extending to other disciplines, and Liu Bang is not talking about class struggle. Not to mention the history circle, even the history of the party will not agree.

2. If we want to define the United front as "divide and conquer, win over those who share weal and woe with the enemy, and defeat the main enemy with the second enemy", then Liu Bang is not the first: Sun Wuzi has the word "attack from far away and attack from near", and Zhang Yi has Lian Heng's strategy, all of which meet the above definition and are earlier than Liu Bang.
