1. Walking alone will not overflow, which means that a person will not aim too high or stagnate halfway if he moves slowly and steadily. As Li Shanglong said, "Loneliness is the best appreciation period."
2. From Mu Xin's poem, the original text: Only when you walk alone can you not overflow. 21st, tomorrow and tomorrow. Sometimes excited, sometimes depressed. Tomorrow and tomorrow, recalling the past calm. Such as the clear sky, the colorless kite of the cause, running to lead high and send far.
