Zhu Qizhen was the only emperor who ascended the throne twice in the history of Ming Dynasty, so why was he called the God of War of Ming Dynasty?

Zhu Qizhen, known as the "God of War in Daming", does not really praise his great achievements, but satirizes his actions. In the tenth year of Xuande, Zhu Qizhen officially acceded to the throne with an orthodox title. There was little doubt about the country, and Zhang Taihou was in charge of all state affairs. He appointed the "Sanyang Cabinet" to be in charge of state affairs, which led to the loss of comprehensive national strength. After eight years of orthodoxy, he officially ruled, made great efforts, and favored Wang Zhen, which led to the eunuch's autocratic power. In the fourteenth year of orthodoxy (1449), the commander-in-chief of the imperial army personally marched and attacked the rising Walla Department of Mongolia, which led to the change of the civil fortress and the defeat and capture.
