The real cause of Chang Yuchun's sudden death in Ming Dynasty. How did Chang Yuchun die?

Here's the story. In May of the second year of Hongwu (1369), General Yuan invaded Tongzhou again, so Chang Yuchun was ordered to lead 90,000 troops out of the fort to make a crusade.

Along the way, the Ming army was invincible, and finally went straight to Kaiping and captured "10,000 yuan troops, 10,000 cars, 3,000 war horses and 50,000 cattle". The army moved troops to Beiping. On July 7th, when passing through Liuhe, Chang Yuchun "suddenly died, only forty years old".

Suffering from the "nail-breaking wind" and sudden death, that is, the current "stroke."

Cause "stroke" disease; With years of injury, the body has reached its limit; Coupled with the army expedition, without a good doctor, he died.

According to the literature, the army marched northward from May to July, which was in summer and autumn, and the weather was hot. On the way, Chang Yuchun had to make a battle plan and arm himself, which was very tiring. Although he looks good on the surface, his health is in a very dangerous situation.

Liuhe is located in Chengde City, Hebei Province. Although the temperature is low in July, the temperature difference between day and night is very large.

It is conceivable that the weather in Liuhe River area is hot during the day, and Chang Yuchun is armed to the teeth. It was cool at night, so he took off his armor immediately, regardless of sweating.

It is in this case that Chang Yuchun suffered "disarming" and sudden death.
