Must: 得 (děi) and 不用
得 (děi) + Verb — 不用 + Verb
得, pronounced děi, means "must / have to" in everyday speech: 我得走了 "I've got to go", 你得多休息 "you have to rest more". Yes, it's the same character as the complement-得 (de) in 说得很好 — the meaning depends on where it sits: before a verb it's děi "must".
The negative is its own word: 不用 (búyòng) "don't need to": 明天不用上课 "no class tomorrow". Never say 不得 for "don't have to" — the opposite of "must" in Chinese is "no need".
