Why did Emperor Yang of Sui make Yang Yu the crown prince and his son?

Yang Guang's crown prince is Yang Zhao, the prince of Yuande, who died earlier than Yang Guang. The second son is Yang Xuan, the king of Qi, who is close to the villain and is hated by Yang Guang. Yang Yu, the acting king, was the son of Yang Zhao, and was later proclaimed emperor by Li Yuan in Chang'an, reigning for one year.

It was not established by Emperor Yang of Sui, Li Yuan invaded Chang'an and made him a puppet emperor.

It was not established by Emperor Yang of Sui. Yang Yu is called the emperor, but he is just a puppet in the hands of Li Yuan.

After Emperor Yang of Sui ascended the throne, Yang Zhao was made the crown prince. In the second year of the Great Cause, when Yang Yu was two years old, his father Yang Zhao unfortunately died. At the age of three, he was made the king of Chen, and later he was named the acting king, and enjoyed 10,000 households.

When Emperor Yang went out on a tour in his later years, he ordered him to stay in Chang'an. In October 617, Li Yuan raised troops from Taiyuan to invade Chang'an. After Li Yuan occupied Chang'an, he did not kill Yang Yu, but supported him as emperor.

In November of the thirteenth year of the Great Cause, the thirteen-year-old Yang Yu, supported by Li Yuan's father and son, was enthroned as emperor in Daxing Palace, changed the year name to Yining, and respected Emperor Yang as Emperor Taishang.

Yang Yu is called the emperor, but he is just a puppet in the hands of Li Yuan.

He was really killed by Yang Guang, because Yang Guang had been looking forward to the throne for a long time and had not been able to succeed to the throne for a long time, so he killed him in anger.

I don't think so, according to the records of the historical books, the Emperor Wen of Sui he said in him died of illness, and it was only in the past few years that some people speculated that Yang Jian was killed by Yang Guang, and it felt unconvincing and reliable.

No, Yang Guang had already become the crown prince at that time, and there was no motive to kill Yang Jian, according to historical records, we can know that Yang Jian died because he was unwell, not killed by Yang Guang.

No, Yang Guang did not kill Yang Jian, Yang Jian was seriously ill and died, and a few days before Yang Jian's death, he also recruited Yang Guang into the palace and told him that the back road had been paved for him.

I don't think it should be, Emperor Wen of Sui has already set up Yang Guang as the crown prince, Yang Guang has no need to kill his father, and according to historical records, Emperor Wen of Sui was very peaceful before he died.
