In the battle of Jingnan, Wen Jian had 300,000 elite teachers in Yunnan. Why didn't he call?

In the battle of Jingnan, Judy successfully ousted his nephew Zhu Yunwen from the throne. At the beginning of the war, Judy didn't have much advantage, but after all, Judy was a vassal king who resisted Vara in the north all the year round. He is better at fighting than his father, and his character is very kind. How can he defeat Judy's army under such circumstances? Although there were 300,000 troops stationed in Yunnan at that time, he didn't think Judy could hit the capital at that time, so he didn't want to mobilize these 300,000 troops to station in Yunnan at the beginning. Judy hit the capital, even if she wanted Mu Ying to lead 300,000 people to rescue, it was too far away to quench her thirst, so she didn't use Mu Ying's 300,000 troops to rescue herself.

The war between Judy and Wen Jian was actually triggered by Wen Jian's behavior, and he just wanted to weaken the vassal. However, at that time, Judy had an inheritance problem between the emperor and his grandson. As a result, as soon as Wen Jian came to power, he began to clean up his uncles, so Judy was very angry and died anyway, so Judy first challenged Wen Jian. At that time, he didn't expect Judy to oppose him, so when Judy started fighting, he was very hesitant. He also had some inexperience in choosing a general to fight Judy, so he gave Judy enough time to adjust and attack in this long battle with him.

He has a kind personality, but he has no combat experience. So in this battle, his character has a great advantage. However, the first time he hurt Judy's life, the second time he was afraid that the generals were insatiable, which made him hesitate to choose a general. Finally, he chose a good man, but he changed it several times. At that time, Judy was cross the rubicon, while Wen Jian was afraid to fight hard and had to fight, which was very tangled.

At that time, Mu Ying's 300,000-strong army was far away in Yunnan, and Wen Jian didn't even want to use it. First, the frontier can't adjust troops at once, otherwise there will be foreign invasion. Second, his understanding of Mu Ying is intense. Mu Ying followed Zhu Yuanzhang and beat him with a malicious stick. If he got Mu Ying's 300,000 troops, how guilty would he be if Judy was killed? Therefore, Wen Jian did not use the 300,000 elite teachers in Muying.
