Never regret

be tireless in teaching

fear of attack from behind

Go straight on

earth-shaking

One's inmost feelings

Prison execution

have a retinue behind and before(with a large retinue)

the redlight district

extort illegal taxes

with ease and verve

gaunt and emaciated

Under an injustice

be harmful to society's morals(lowlife)

Gossip

Fancy

disappear

Corruption is rife.

Carefree and peaceful life

The wild geese are crying mournfully.
