I have long heard that epiphyllum only blooms for one night. This is the first night. And the last night. Philosophy full of impermanence of life is determined to meet its enlightenment.

1. Everything is uncertain. We can never predict what will happen in the future. It is philosophy now, which may be overthrown later. Only endless and vigorous development. This sentence tells us to respect life, cherish life and take our destiny into our own hands.

The description of epiphyllum in the context shows that epiphyllum is different from other flowers. It waits silently, gathers strength and blooms beautifully. We should grasp the two key words "hard work" and "impermanence" to understand. "Struggle for life" means that the epiphyllum blooms bravely and resolutely, which is extremely brilliant; "impermanence" means that epiphyllum is different from other flowers. It blooms in the silent night, short and without reservation. A person's life may be to seize every rare opportunity and release his brilliance. Don't hesitate too much. On the other hand, have the courage to do it! It is that kind of momentum and courage.
