Youth is not a time of life; it is a state of mind; 青春不是年华，而是心境；it is not a matter of rosy cheeks, red lips and supple knees; 不是桃面、丹唇、柔膝，it is a matter of the will, a quality of the imagination, a vigor of the emotions;
而是深沉的意志、恢宏的想象和炽热的感情；it is the freshness of the deep springs of life.青春如生命的深泉在涌流。
