She lived a life of no promise like most people, doing what she should do at the age she should do, but what she wanted was never such a life. She wanted to be as wanton as Li Ansheng in the movie.

She was reborn. She wanted to change herself. She had been a good child in the eyes of her elders for twenty-eight years. She had had enough. Next, she just wanted to be herself.
Cool article, don't delve into logic or anything like that.
