wear one's heart on one's sleeve

Defeated troops and brave troops

set the wolf to keep the sheep(throw the door open for the robbers)

a frog in a pit(a person with a very limited outlook)

a pretentious and empty person

spacious and deserted

cannot suit for one's idea(turn up one's nose at)

warm the cockles of the heart

cudgel one's brains (to evolve an idea)

with vigorous strides(at a stride)

Write in an ornate style

talk high, wide, and handsome

Cry bitterly

boast(utter bold words)

leave nothing usable to the invading enemy

A fast job done by a straightforward person

to treat people according to their rank and one's relationship with them (idiom)​

a cur barking at the sun

conjecture on the basis of reason

withered trees and rotten stumps
