If a woman is 25 years old, then she is so young and beautiful, a time when she is no longer ignorant and has not been completely baptized by the world. But if a woman's age stays at 25 forever, then what she will get is an unchanged appearance, a permanent consideration, and a memory of the past. Her appearance has not changed, but her mood has changed. Her love is still there, but she cannot regain the vagueness she had before. People are still there, love is still there, but they are no longer what they were before. Reality has given them too much, such as family affection, responsibility... Not only love. The first time I saw him, he was 7 years old, and she gave him warmth; the second time I saw her, he was 17, in his youth and in love; the third time I saw her, he was 23, in his prime; the fourth time I saw her, he was 40, mature and modest; the last time we met, we were separated by life and death. This woman has experienced the turbulent Republic of China, the reform and liberation of New China, and the rise and development of China. Everything is changing. What remains unchanged is her appearance and her love. She is waiting for the final passage of time... She said that if she could choose, she hoped to grow old with him...
