I just know that Cao Caoqiang can't attack. When Jun rushed to Wu Chao Chunyu Qiong Barracks, Yuan Shao's reinforcements were approaching. Cao fought to the death, defeated, killed Chunyu Qiong and burned all his food.
The news that Wu Chao's grain and grass were burned spread to the front line in Yuan Jun, which shook people's hearts and divided them internally. Cao Jun took advantage of the situation and defeated Yuan Jun .. Yuan Shao returned to Hebei in a panic with 800 riders, and successively annihilated and trapped more than 70,000 Yuan Jun.

Cao Cao's army, led by Tian Chou, climbed up Xuwu Mountain and went out of Lulongsai, "more than 500 miles in the valley", pointing to Liucheng, Wuhuan's lair.
In less than two hundred miles from Liucheng, Wu Huan found that Ta Dun, Yuan Shang, Yuan and others led tens of thousands of cavalry to meet him. In August, when the two armies met, Cao Jun was behind the trench. Soon, Gongsun Kang killed Yuan Shang and Yuan, and presented their heads to Cao Cao.
