When Toyotomi Hideyoshi was ready to invade China, what was China's strength?

At that time, China experienced Zhang's political reform, and Daming got ZTE, which was relatively strong. However, Zhang Juzheng died in the 10th year of Wanli, that is, 1582, and the Emperor Wanli began to slack off in political affairs, and the Ming Dynasty began to decline. Japan invaded Korea from twenty years to twenty-five years of Wanli, which was a process from prosperity to decline. The Korean War dealt a great financial blow to the Ming Dynasty and accelerated its decline, but the war was maintained by the Ming Dynasty.

During the Zhang period, the Ming Dynasty was well armed. Even in the late Ming Dynasty, it was because Zhang reused Qi Jiguang and other outstanding generals. Therefore, even if Japan had South Korea as a springboard, it could not win, and the national strength of the two countries was not at the same level.
