without beginning or end(without head or tail)

Four wonders

to plan to seize power of the whole country (idiom)

be elegant in manner, attitude and speech

be dignified but not violent

broadmined and knowledgeable

as if in front of eyes

have no desire to continue fighting

master key

pour water off a steep roof

river of literacy, sea of learning (idiom); ars longa, vita brevis

All in silence

Critical remarks

Lay the blame on others

spiritual friendship between a noble and a commoner

Inside and outside

show the feebleness of old age while still young

Regret deeply

be on the safe side(have every change of success)

Gallop ahead with sword drawn
