After Yang Guang ascended the throne, he governed the country with his own management methods. When he was in the King of Jin, in order to win the love between Queen Dugu and Emperor Wendi of Sui Dynasty, he led troops to fight many times and achieved immortal results. When he succeeded to the throne, his true nature was revealed. In order to build the Grand Canal, he plundered the people's butter and fat, broke the people's life of living and working in peace and contentment, and also attracted people to lament. Such a Sui Dynasty was destined to be replaced by others. Sure enough, Li Yuan appeared and led soldiers to conquer the Sui Dynasty and establish the Tang Dynasty.
Yang Jun, the remaining sons of Emperor Wen, was also very dissatisfied with Emperor Wen because of his personal style, which led to Emperor Wen finally having to change his position and relegate him to a place similar to the cold palace. In the end, Yang Jun died at the age of 30, while Yang Jun died young.
The following Shu kings, Yang Xiu and Yang Liang, did not have a happy ending. Yang Xiu, King of Shu, bullied him because of his hedonistic personality and his status as a prince, which led to Emperor Wen's great dislike for him. Finally, Wendi put him under house arrest, because he refused to accept Yang Guang as the prince, so he planned to mobilize troops to revolt, but ended in failure. Finally, Wendi put him under house arrest.
Although Emperor Wendi was a great monarch, he never handled the relationship between his sons well, which eventually led to his son's death and house arrest, all because of Emperor Wendi's mistakes in education. As the saying goes, it is wrong to raise a father. The sons of Emperor Wendi of Sui Dynasty ended up in a bad ending because of the failure of Emperor Wendi's education.
