When people reach middle age, they are most unwilling to face aging, their lover's change of heart, and their children to leave. The most unwilling thing is to stand in the middle of life and look back: the spring is gone and it is difficult to come back. Looking forward: the twilight is hazy and the heart is uneasy.
Reluctant, unwilling, who knows that there will be no less in life? The water flowing in front of the door can still flow to the west!
