Why does Queen Dugu like Yang Guang instead of Prince Yong Yang?

Yang Guang is Garro Dugu's second son, but he is not the most favored one. Because Garro Dugu was mainly a feminist, he insisted on monogamy and attached great importance to Emperor Wen of Sui Dynasty. Emperor Wendi of Sui Dynasty also became the first emperor without other women in the harem in history, but it was very sad behind his seemingly infatuation. The couple's favorite is Prince Yong Yang.

Yong Yang is kind and excellent. As the eldest son, he is naturally loved by his parents. Compared with him, Yang Guang's position is lower, but the advantage is that he is smarter. Yong Yang thought he had made a contribution, and the prince began to become arrogant. He did a lot of things that made Queen Dugu and his wife have a headache, and their patience was exhausted.

For example, life is too extravagant and attaches great importance to enjoyment. Even the birthday party is comparable to the emperor, and it is more ostentatious than Emperor Wendi's father. In addition, Emperor Wendi of Sui Dynasty did not like luxury, and he became more and more disgusted with what this son had done. In the end, even the Queen Dugu abandoned him just because he violated monogamy and spoiled his wife. With Yong Yang in the front, Yang Guang kept a low profile and tried to show the best side to Queen Dugu. After a long time, her views on her second son also changed, and she even began to persuade Emperor Wen of Sui to set up another prince.

Later, he wooed the North Korean veteran to stand on his side. This man is Su Yang. With his help, Yang Guang's position suddenly stabilized, and she became the default heir of Queen Dugu. Yong Yang, who was originally in the position of prince, was squeezed down, and he succeeded. Unfortunately, the couple didn't expect that the big Sui Dynasty, which was finally established, died after only two generations.
