Older people who seek wood must be solid; Those who want to flow far, dig their springs.
Dedicated to work, wide-ranging and diligent.
Empty talk about wrong country, hard work and prosperity.
Only when it is difficult can you be brave; Only by tempering can we achieve.
Teenagers only know how to play, but don't know how to study hard. When they are old, they regret why they didn't know how to study hard when they were young.
