Both 疲 (ひ, tired) and 弊 (へい, wear out/damage) are On'yomi. It describes a state of extreme exhaustion, weariness, or deterioration, often leading to impoverishment or a weakened condition for people, systems, or economies. Incorrect readings like ひひ or ひほう misread 弊, and へいひ reverses the order.

疲（ひ）と弊（へい）は共に音読みです。極度に疲労したり、機能が衰えたりして、活動力が低下した状態を指します。ひひやひほうは弊の誤読、へいひは字の順序が逆です。
