How did Fifth-Age Yongqi, the favorite son of Emperor Qianlong, die back then?

Fifth Brother Yongqi finally died of illness. We have all seen the "Return of the Pearl", which Yongqi very much loved by the emperor, has been Qianlong want to pass the throne to the person, but did not expect Yongqi died in front of Qianlong. Although the fifth brother Yongqi could write and fight, but the fact is that his health is not very good! When we watched "Returning the Pearl", it didn't show Yongqi getting sick a lot, but he just ended up dying at a young age because of a lot of illnesses that built up and couldn't be cured anymore.

While it didn't show Fifth Brother getting sick a lot, but when we watched the third part! At that time when the Old Buddha asked Yongqi to marry Zhi Piao, we could see that Yongqi was not in good health! Because at that time, the old Buddha said that Yongqi must hurry to have an offspring, which can be punched, and Xiao Yanzi is also not born, then only to marry another one! In ancient times, the joy of rushing is usually the male member of the family is sick or not good health, want to recover quickly.

It can be said that Yongqi and Zhi painting were not married for a long time, Zhi painting had a child! Yongqi often cough, and then did not care too much, just took a little medicine prescribed by the eunuch. Then not a few years Yongqi body began to weaken, the doctor said the disease has been deep, can not maintain too long.
