When she was six years old, she saw her twin sister sleeping peacefully in the river. Later, she always thought of her. She was afraid of looking in the mirror, afraid of thinking of the dusk and her pale face. So she always told herself over and over again that it was just a little joke God played on her, and that the memory was just disrupted in the summer. Later, she closed herself in the dust and learned her appearance, her speaking movements, her sleeping expression, her walking posture, and her favorite songs. Until later, she met Jiang Chuan, and he said, "Your name is Youlan?" She replied, "My name is Lanyou. Youlan seems to be the loneliest flower." She met Lu Manman, a girl who looked very ladylike, but was not ladylike at all. Later, she remembered the meaning of her name when she said it with great vigor. The road ahead is far and long. I want to go to heaven and earth to find the sun in my heart. And Jiangchuan is the sun of her life, teaching her to forget and grow.
