Is Judy's Five Signs of Mobei really that useful?

I'm sure I can open my mouth and tell what the five expeditions of Emperor Yongle were and what the specific results were. I find it hard to say. The remnants of Mengyuan fled far away, but Judy returned in vain and died when she returned to Yumuchuan.

In the first month of the eighth year of Yongle in the Ming Dynasty, Judy decided to lead 500,000 troops to attack the Mongolian Tatar Department because the Ming army was defeated by the Lu Canal River. Before the war, 30,000 military vehicles were specially prepared, and it is planned to transport 200,000 stone grain with the army, so as to store grain in stages along the way and facilitate the return. In March of the 12th year of Yongle in Ming Dynasty, Judy led 500,000 troops out of Beijing and personally conquered the Wula Department. The army arrived in Xinghe (now Zhangbei, Hebei), held a grand military parade, and then went north.

Judy led an army out of Beijing with 300,000 troops, 340,000 donkeys, 0/77,000 vehicles, 235,000 population and 370,000 grain. In Yongle 2 1 year, when Arutai IV went to Mobei, he constantly harassed the frontier towns of the Ming Dynasty. Judy wanted to destroy it in one fell swoop, so he led another 300,000 troops on a personal expedition. In March of the 22nd year of Yongle in Ming Dynasty, Emperor Judy and Arutai, the leader of Mongolian Tatar Department, repeatedly harassed the frontier defense. He accepted the advice of the officials and asked the generals to do it themselves.

On the surface, Judy's five expeditions to Mobei were five victories, but in fact, these five expeditions did not cause substantial losses to the north, but caused greater losses to her own side. Because for the Ming army, this kind of March in different places, not to mention the climate, long-distance raid, insufficient supply of military salaries, too long front and other problems, consumed a lot of resources. Yang Rong and Jin Youzi are important officials of the imperial court. In order to conceal Judy's death, they thought of sealing Judy's body with tin, thus successfully concealing Judy's death and directly contributing to the smooth handover of the throne in the Ming Dynasty. Although this practice is deceptive, it is of great significance to the history of the Ming Dynasty. Otherwise, it is not clear whether Judy's heir to the throne is Ming Renzong.
