2. Tao Qian made an enemy with Cao Cao because Cao Cao's father died at the hands of Tao Qian, but this is not the case. Tao Qian and Cao Cao already had bad blood and hatred, but it didn't break out yet, and Cao Song's murder completely aroused the contradiction between Cao Cao and Tao Qian.
3. To understand the origin of the discord between Tao Qian and Cao Cao, we must first understand the situation at that time. At that time, it was the time when the Han Dynasty fell out of power and the princes merged. At that time, the two most powerful governors in kanto region were Yuan Shao and Yuan Shu. If these two men join hands, they can destroy Kanto, but they are hostile, so they look for allies separately. Yuan Shu's main allies were Gongsun Zan and others, while Yuan Shaoze wooed Liu Biao and Cao Cao against Yuan Shu.
4. As for why Tao Qian made an alliance with Yuan Shu, it was because Yuan Shu, after all, was the son of the Yuan family, occupied the best territorial resources and was the most powerful vassal at that time. And at that time, most of Cao Cao's forces were entrenched in Qingzhou and Yanzhou, and they were close to Xuzhou in Tao Qian, which posed a certain threat to the development of Tao Qian, so the relationship between them naturally became hostile.
5. At first, Cao Cao's strength was not strong enough, and Tao Qian took the initiative to attack him. After the failure of the first attack on Cao Cao, Tao Qian never gave up defeating Cao Cao, and then he joined forces with a man who claimed to be the emperor without authorization, and later he killed him. It was a big move at that time to unite with a man who claimed to be the son of heaven. At that time, Cao Cao was still loyal to the Han Dynasty, so in Cao Cao's mind, it was impossible to let such a Tao Qian go. Therefore, the feud between Tao Qian and Cao Cao has a long history.
6. As early as before, Cao Cao and Tao Qian forged a feud because of the feud between princes, but because they could not find a good excuse, Cao Cao was not like Tao Qian. Later, the death of Cao Song, Cao Cao's father, became an explosive barrel, completely detonating the hatred between Cao Cao and Tao Qian.
7. At that time, Cao Song lived in Xuzhou, and Tao Qian sent someone to send Cao Song to Cao Cao's men. However, a minister named Zhang Kai killed Cao Song because he was greedy for Cao Song's money. Others say that Tao Qian personally ordered the killing of Cao Song. Anyway, in Cao Cao's view, Cao Song's death at the hands of Tao Qian just gave him a reason to attack Tao Qian, so Cao Cao raised the banner of revenge for his father and attacked Xuzhou all the way. However, although Cao Cao wanted to personally kill Tao Qian to avenge his father, Tao Qian died of his own sorrow for Cao Cao, not Cao Cao.
8. Tao Qian and Cao Cao were both famous governors and warlords at the end of the Eastern Han Dynasty, and both held high positions at that time. Before Cao Cao's father, Cao Song, was killed, they had feuds over territorial disputes. After Cao Song's death, the contradiction between them intensified completely, which made Cao Cao attack Xuzhou in a rage. Tao Qian first found the wrong opponent, repeatedly provoked Cao Cao, and then killed Cao Cao's father. Naturally, I died of worrying about Cao Cao.
