The relevant famous sayings are as follows:

1. Birthdays are the scales on the ruler of life, but they can only mark the length of a person's life and cannot measure the depth and thickness of life.

2. What measures the value of life is not the length of life, but the width of life. So what matters is not how many days we live, but how we spend them.

3. True love should transcend the length of life, the width of the heart and the depth of the soul.
