Don't sigh that life has been quiet for several years, and the years are like running water halfway up the mountain.

Don't sigh a few years of life. Years and months flow like water halfway up the mountain. It is what poets do when they feel that life is impermanent and enjoy it. These four sentences mean that when people reach middle age, it is like coming to autumn in the cycle of four seasons. Sit down quietly and savor these beautiful years, feeling like running water passing away. Peace of mind, not inexplicable sadness.
