lên voi xuống chó

Etymology
Literally “going up as high as sitting on an elephant’s back, going down as low as a dog"; perhaps alluding to the fact that ancient monarchs and commanders rode elephants while dogs were considered lowly animals used for guarding.

Verb

 * 1)  to have ups and downs in one's life; to go from rages to riches and/or riches to rags; to move up and down the socioeconomic ladder
