W. Mao Mu
This is Mao Mu's essay "Middle Age, Old Age", which reflects on the life of middle age and thinks that it is actually a period of life and career, and the greatest gain of old age life is the liberation of physical and mental freedom, that is, the greatest freedom in spirit, which is the greatest compensation for young and middle-aged people bound by career life and gets rid of the gloomy mood of old age complex.
