官渡之战
The Communist leader Mao Zedong, in his writings about strategic retreat, used the Battle of Guandu along with the Battle of Chenggao, Battle of Kunyang, Battle of Red Cliffs, Battle of Xiaoting, and Battle of Fei River to illustrate the concept. In all of these battles, he wrote, "...the contestants were unequal in strength, and the weaker one yielding a step at first, pinned down the stronger one through delayed action and defeated him." Mao's words attracted some attention to the battle, and many papers were written to analyze the Battle of Guandu in Maoist terms. The Maoist interpretation, while taking note of Yuan Shao's serious errors of judgement, advocates that the strong enemy will make fateful errors, while the weaker opponent need only to await their appearance. The Marxist interpretation portrays Yuan Shao as the representative of the great landlord-official class, and Cao Cao as of the middle and small landlord class. The battle was thus a product of class conflict in which Yuan Shao's fall was inevitable.
