非得

• Pinyin: fēi děi
• Hanzi breakdown: 非 = 非 (negation); 得 = 彳 + 见 (movement + see — to attain/must)

Meaning

Must absolutely; have to without exception. A strong adverb expressing that something is absolutely necessary or unavoidable, often with an implied element of stubbornness or insistence.
