Strive for strength,
Forget to eat and sleep,
Day and night,
bleed
, arduous,
Work hard and complain,
Angry and forgot to eat,
Grind the needle with a pestle,
Strive for the upper reaches,
Self-improvement,
Not afraid of trouble,
Perseverance,
Go all out,
Drip wears away the stone,
A jade can travel a thousand miles in ten days, and a horse can travel a thousand miles in one day-people with low ability can also achieve their goals through perseverance.
