What does it mean to dream after a lifetime of ups and downs?

Half-life ups and downs-half-life has passed, and I have been living in ups and downs. Wash your dreams with lead-wash away the disguised secular appearance, do not apply makeup, do not hide your heart, and have a fresh and refined, elegant and elegant temperament.

Washing away lead is a Taoist philosophy. Similar verse:

Half ups and downs, half sober, half confused.

Ten years are wasted, people are old, and the ups and downs of the rest of their lives are still cold.
