achieve mastery through a comprehensive study of the subject

at the summit of one's power

as if nothing were wrong(without compunction)

Classical Confucian texts

easily done(as though hot water were poured upon snow)

as if having the game in one's hands

look like a man who is drunk or dreaming(with one's mind in a haze)

cleave together as firmly and inseparably as glue and lacquer

cannot help laughing(simmer with laughter)

Time and tide wait for no man.(Time stays for no man.)

Draw over

allow oneself to be insulted to remain alive

pierce somebody's ear like thunder

the sun and the moon shine again

God's country

eat humble pie(swallow an insult)

individual thinking is as varied as individual looks

Change with each passing day

be as if drunk(inebriety)

Harm the country and bring calamities on the people
