1. The situation waits for no one, and the old man's hair grows into silk. ——Li Bai

2. The prime years will never come back again, and it is difficult to come back to the morning every day. You should be encouraged in time, and time waits for no one. ——Tao Yuanming

3. The deceased is like a man, never giving up day and night (Confucius)

4. In life, if a white horse passes through the gap between heaven and earth, it will happen suddenly. (Zhuangzi)

5. The sky can be mended, the sea can be filled, and the southern mountains can be moved. The sun and the moon have passed and cannot be traced back. (Zeng Guofan)

6. Today again today, how little today is! If you don’t do it today, when will this happen? (Wen Jia's "Today's Poems")
