Bow to sb.

old friends are not to be neglected

seclude and avoid worldly care

towering into the clouds and covering up the sun

explore the essence and explain the gist

sniffle and be unable to speak

righthand men

Behave correctly and cautiously

Concentrate on one's work

go beyond the mark(go too far)

Be solitary and modest

Heal one's family

a deep-rooted love for natural charms

a dog wagging its behind(obsequious)

Lose heart

be knowledgeable and efficient

father's instructions

one's cricumstances or characters remain unchanged

Observe customs and customs

excellent wine and delicious dishes
