Long years, busy, busy people are self-improvement; The world is broad and humble; Wind, flowers, snow and the moon are idle, and worry is redundant; Tian Xingjian, a gentleman strives for self-improvement; The terrain is Kun, and the gentleman carries things with morality; Do not disgrace the mission, just look at the flowers in front of the court; Going or staying is unintentional, and it is easy to follow the clouds. Don't take, don't give, don't dream, don't take, be convenient and happy with others.
