But although he has so many sons, his first son has only three. Gan Long attached great importance to Di Zi all his life, and his first wife was Empress Xiaoxianchun Fu Cha. Fu Cha married Gan Long when he was a prince. They are a young couple. Besides, Fu Cha is very beautiful, gentle and virtuous. At that time, Emperor Qianlong loved Fu Cha very much. Fu Chashi gave birth to two princes for Qianlong, namely Yong Lian, the second son of the emperor, and Yongcong, the seventh son of the emperor. At that time, Yong Lian was very clever and worked very hard since he was a child. He was very popular with Qianlong, who secretly named him Prince. Unfortunately, Yong Lian died when he was only nine years old. Later, the emperor's sixth son, Yong Cong, was born in Fu Cha and also died of acne rash at the age of 2. Fucha, the Empress of Xiaoxianchun, later died in the shock of losing two sons in succession.
As far as the relationship between Fu Cha, the filial piety queen and Emperor Qianlong is concerned, if Fu Cha's two sons were really killed, Qianlong, who was in his prime at that time, would not be investigated in the harem, and his harem could not be without warning. Moreover, as can be seen from the names of Fu Cha's two sons, both Yong Lian and Yong Cong implied the meaning of bearing the instrument, and how highly the Emperor Qianlong valued the two princes. So if those two Di Zi didn't die of natural causes, Emperor Qianlong wouldn't let those who murdered Di Zi in the harem go so easily. At that time, Yong Cong died of smallpox. Since the Qing dynasty entered the customs, many royal children have died of this disease. At that time, even the emperor shunzhi died young because of this disease.
So at that time, the mortality rate of this disease in the Qing Dynasty was very high. In fact, the medical level in ancient China was very poor. Even in the court, not many young princes can grow up. So all the princes set by Qianlong died of illness.
