Spring returns to the earth and everything comes back to life.
Tips
history
The four-character set phrase 妙手回春 ('skilled hands bring back spring') is a high compliment for a doctor - likening recovery from illness to nature reawakening after winter. Calligraphic plaques with these four characters are still given to physicians as gratitude gifts in mainland China and Taiwan.
usage
Two distinct senses: literal seasonal return (大地回春) and medical revival (起死回生 / 妙手回春). Also extends to renewal in art, business, or fortune: 老树回春 ('the old tree blooms again').
