If he followed Tian Feng s advice, would Yuan Shao definitely be able to defeat Cao Cao and dominate

I think it's okay, because Tian Feng's suggestion just hit Cao Cao's death hole, as long as Yuan Shao listened, then he would definitely make Cao Cao's army suffer heavy losses, and naturally he could defeat Cao Cao. Moreover, he had the largest power in the world at that time, as long as he defeated Cao Cao, he would naturally be able to dominate the world.

Not necessarily, but if you listen to Tian Feng's advice, Yuan Shao will not lose in the battle of Guandu, Yuan Shao should listen to Tian Feng's advice and keep his eyes on it.

I think that if I followed the plan, I should be able to defeat Cao Cao, because Yuan Shao's forces were very strong at that time.

Yes, because Tian Feng is loyal and righteous, and his strategy is very skillful, it can be said that it is more than enough to deal with Cao Cao.

In "Romance of the Three Kingdoms", the reason why Yuan Shao wanted to detain Tian Feng was because Tian Feng was outspoken and angered Yuan Shao.

When Cao Cao attacked Liu Bei in Xuzhou, Liu Bei asked Yuan Shao for help, and Tian Feng thought that the opportunity was rare and urged Yuan Shao to send troops to attack Xudu. But Yuan Shao refused to send troops because his youngest son Yuan Shang was ill at this time. Tian Feng bluntly admonished, the opportunity is rare, how can he miss a great opportunity because of his son's illness.

When Yuan Shao heard this, he became disgusted with Tian Feng and began to snub Tian Feng.

Later, Yuan Shao decided to attack Cao Cao and rebelled with the strategists, most of the strategists thought that Yuan Shao was strong at this time, and it was easy to defeat Cao Cao, so they supported Yuan Shao to send troops to attack Cao. Tian Feng believed that Cao Cao coerced the Son of Heaven to order the princes, and was very good at employing people, good at using troops, and bluntly admonished Yuan Shao not to rush into the army, and should use durable tactics to consume Cao Cao, so as to defeat Cao Cao, if he was eager to attack Cao Cao, it was just conducive to Cao Cao, and even bluntly said that he would be defeated if he advanced lightly. This offended Yuan Shao, so Yuan Shao ordered Tian Feng to be detained.

Yuan Shao marched to attack Cao Tan, held each other in Guandu, and fought a decisive battle in Guandu, known as the "Battle of Guandu" in history. The Battle of Guandu was a famous battle in which the weak defeated the strong, and Yuan Shao was defeated by Cao Cao despite being strong. Yuan Shao regretted it, Yuan Shao said, Tian Feng stopped me before he set out on the expedition, and I regretted very much that I didn't listen to his advice.

Although Yuan Shao had many advisers, they were incompatible with each other, disagreed, and even defended each other and framed each other. The strategist Feng Ji then slandered in front of Yuan Shao, saying that Tian Feng heard that Yuan Shao's Guandu army was defeated, clapped his hands and laughed, and was very happy, saying that Yuan Shao would not have caused the defeat of the army when he listened to his advice. Yuan Shao was furious when he heard this, and without thinking about it, he ordered Tian Feng to be executed.

Because Yuan Shao "is generous and elegant on the outside, there is a degree of locality, and the joy and sorrow are invisible, and there are many taboos inside." Therefore, most of the strategists who dared to speak out were snubbed, whether it was Tian Feng or frustrated teaching, they were all feared by Yuan Shao because of their outspokenness, or they were detained or arrested and imprisoned, or even executed.

This also doomed that although Yuan Shao was strong, he could not fight Cao Cao, who was weaker than himself.

It is because the other party has really done some particularly bad things, and it has directly affected many people, so they will be detained.

Tian Feng did some bad things at that time, offended many people, and also posed a threat to Yuan Shao's status, so he was imprisoned.

is because when Yuan Shao was defeated, Tian Feng gloated, and then offended Yuan Shao.

The other party has done some bad things, and after detaining the other party, he has to investigate some things, so he will do this.

After the Battle of Guandu, Yuan Shao did not listen to Tian Feng and Fu Zhu's advice, and the result was a fiasco.
