very precious treasures

fan one's parents' pillow in summer and warm their quilt with one's body in winter

After having broken his upper arms for three times, he becomes a good surgeon.

pay dear for one's whistle

grief of losing one's son

tyrannize the people

Food pot

(of troops) carry all before one(sweep away all obstacles)

self-appreciation

more than one can shake a stick at

a place where one is apt to get into trouble(hotbed of rumours)

four seasons and eight solar terms

Water and fire do not escape

bid farewell to a departing friend

study from others on halfway and thus lose one's own strongness

behave according to decorum(toe a line)

Ask others for help

It is no use crying over spilt milk.

rat's liver and insect's legs(worthless things or infinitesimal parts of creation)

Ask others for help
