Why did Li Chenggan, a brick in the Tang Dynasty, rebel against Li Chenggan and finally become emperor?

In the TV series Brick of the Tang Dynasty, Li Chenggan, as the eldest son of Li Shimin and his grandson, received much attention from an early age, and was made a prince at an early age. But Li Chenggan chose to betray Li Shimin, so why did Li Chenggan rebel? As long as Li Chenggan grew up honestly according to Li Shimin's arrangement, the throne would be his sooner or later, but Li Chenggan chose to use rebellion to achieve his own goals, which not only hurt himself, but also hurt Ye Yun and Xin Yue.

Li Chenggan was made a prince by Li Shimin when he was very young. He had to attend classes in an appropriate way every day. Li Chenggan's superficial scenery, in fact, has no freedom at all. Because Li Chenggan is a prince, his words and deeds must conform to everyone's impression of the prince. Everything Li Chenggan does must be approved by Li Shimin and his grandson.

Li Chenggan grew up in such a big environment, and he lived according to the requirements of Li Shimin and his grandson. From life to career to feelings, Li Cheng can't help anything. For example, Li Chenggan and Lu Xinyue liked each other, but in the end they married Su Wan, and even Lu Xinyue's family couldn't reach out to save her life.

For the safety of Xinyue, Li Chenggan let his good brother Ye Yun marry his favorite Xinyue, and watched his sweetheart marry someone else's wife. This incident became the fuse of Li Chenggan's blackening and ignited Li Chenggan's dissatisfaction with Li Shimin and others.

Originally, Li Chenggan thought that as long as he lived according to the requirements of Li Shimin, he would get everything sooner or later. But Li Chenggan was under great pressure of study and life, and finally he was deprived of the opportunity to be with his beloved.

Coupled with Hou's malicious intentions, he had long wanted the following people to offend others, so he used things to stimulate Li Chenggan and persuade Li Chenggan to fight for his throne. As long as they succeed, these things are still Li Chenggan's, otherwise they may not be.

In order to be with the fair and square, Li Chenggan quietly prepared to rebel at Hou's instigation, but Li Chenggan wanted nothing but to be with him, even if he betrayed the whole world, it didn't matter. Finally, he killed Xinyue, was imprisoned by Li Shimin, and died of depression.
