Princess Lanling was the apple of Emperor Wendi's eye, but why was she killed by her own brother?

Princess Lanling is the youngest princess in Yang Di. She was the apple of her eye since she was a child, but the ending was quite tragic. Princess Lanling was married twice, and the second husband offended the newly appointed emperor Yang Guang, so he exiled her husband to Lingnan. In order to maintain political power, Yang Guang proposed to Princess Lanling three times, but the princess refused, and even wanted to go into exile with her husband, expressing her willingness to give up her status as a princess, but Yang Guang refused to let her go and imprisoned her in the palace. Finally, the princess died in grief and indignation.

Princess Lanling is clever, gentle and moving since she was a child, and she is the treasure of the family. When she gets married, it will be a thousand choices. Fearing that the princess would be wronged, she chose Wang Yi, the son of the powerful minister. Wang is a gentle person and is very kind to the princess. The princess is very happy in Wang Jiasheng's life. Later, Emperor Wendi proclaimed himself emperor, which was the official seal of the princess, but it didn't last long. The princess was heartbroken when the king died of illness. Even if Wang Yi and his wife advised the princess to remarry, the princess refused.

Later, Wang Yi offended Emperor Wendi politically and was sentenced to death, so the princess returned to her parents. At this time, the princess was still young, and the Sui Wendi couple wanted to choose a good husband for the princess. This time, they married Liu Shu, the son of Liu Ji, who was regarded as an etiquette. After the princess married Liu Shu, Liu Shu treated her very well. Emperor Wendi loved her daughter so much that she even rose to the position of Liu Shu. However, Liu Shu's personality was so arrogant that Emperor Wendi of Sui Dynasty could not stand it and punished her.

Later, Emperor Wendi died and Yang Guang succeeded to the throne. Sitting on the throne, Yang Guang tore off his hypocritical face, killed his younger brother Yong Yang, imprisoned his younger brothers Yang Xiu and Yang Liang, and even Liu Shu was exiled to Lingnan because he had offended Yang Guang before. Yang Guo also wanted Princess Lanling to remarry, but at this time, Princess Lanling was completely disappointed with Yang Guang and was no longer willing to listen to him. She wants to go into exile with Liu Shu, even.
