As long as you work hard enough, an iron pestle can be ground into a needle; there are roads in the mountains, and diligence is a path, and learning is boundless, and hard work is a boat; if you don't get up early in the morning, you will miss a day's work; if you don't study hard when you are young, you will miss a life's work ; Genius is ninety-nine percent sweat and one percent inspiration; the lights are on at three o'clock and the chicken is on at five o'clock, which is when men study; history makes people wise, poetry makes people smart, mathematics makes people precise, and philosophy makes people Profound, ethics makes people solemn, logic makes people eloquent; love of learning leads to diligence, and diligence leads to genius; diligent study leads to success, but lack of diligence leads to an empty stomach; genius is the ability of endless hard work and diligence; industry excellence comes from diligence but waste from play, Actions are accomplished by thinking and destroyed by following.
