have learned from the same master but started one's own school

make a mystery of

One's age is reckoned with that of the crane and the tortoise.

bear a debt of gratitude

Crowd of spectators

The audience is like weaving.

probe into the reasoning of something abstract

Praise no man till he is dead.

Bitter as if it were malt sugar

ready to die the cruelest death

replace the beams and pillars with rotten timbers

get up to mean or petty tricks

Change the tune

carry through to the end(drive the nail home)

pleasantly consuming it as if taking sugarplums

glorify one's forefathers and enrich one's posterity

let loose wild shrieks and howls

look at flowers in a fog(have a blurred vision)

singsong stages and dancing halls

high walls and deep moat
