a child daring to do great mischief

swallow one's leek(pocket an insult)

The man perisher,but his property remains

to look blank(feel as if something were missing)

late in the morning

that's what it all adds up to

eat humble pie(put one's pride in one's pocket)

military tactics of the human sea

burn/consume the midnight oil

The soft intestines turn a hundred times.

regard enemies as father

In straitened circumstances

Soft and fair goes far.

A kindly man of high character

feel like standing upon the edge of an abyss

On entering a country, inquire about its customs

Forge ahead

pathetically anxious(pathetic anxiety)

mess around with love affairs

In one's humble position, one's word does not carry much weight
