Youth is not a time of life; it is a state of mind;

青春不是年華，而是心境。

it is not a matter of rosy cheeks， red lips and supple knees;

it is a matter of the will， a quality of the imagination， a vigor of the emotions;

青春不是桃面、丹唇或柔膝，而是深沉的意志、恢宏的想象、熾熱的情感。

it is the freshness of the deep springs of life.

青春是生命的深泉在涌流。
