Write 反(fǎn)(opposite) in Chinese character

反（fǎn）
Origin:

骨文中，“反”字像一只手正向着崖边攀登，是“攀”的本字，后来本义消失，意思变为“相反”、“反叛”。
On ancient oracle bone inscriptions, “反” looks like a hand climbing cliff, making it the original character of “攀” (to climb). Then, its original meaning disappeared, changing to “opposite” or “rebel.”

Meaning:

opposite; contrary; turn over; return

Words:

 反复(fǎnfù): repeatedly

反馈(fǎnkuì): feedback

相反(xiàngfǎn): contrary
