保健
bǎojiàn · HSK 6
care for one's health
🏥 保 = protect + 健 = healthy → protecting health = health care
保 (bǎo) means protect or guard; 健 (jiàn) means healthy or strong. Together they form the verb-object idea of safeguarding wellness — what English calls health care or health maintenance.
保 — person 亻 + 呆 (child/protect phonetic)
Originally an ideograph showing an adult carrying a child on the back, meaning to protect or shield. The right side 呆 evolved from a depiction of a swaddled infant. Over time the meaning broadened from 'protect a child' to 'preserve, guarantee, keep safe.'
