Common mix-ups
不 vs 没
bù vs méi
不 usually denies habits, choices, future actions, and adjectives. 没 denies that something happened or exists.
我不去 = I will not go; 我没去 = I did not go.
wǒ bú qù; wǒ méi qù
别 vs 不要
bié vs búyào
Both can prohibit an action. 别 is compact and common; 不要 can sound more explicit or warning-like.
别走 and 不要走 both mean do not leave.
bié zǒu; búyào zǒu
不是...而是... vs simple negation
bú shì... ér shì...
Simple negation only denies. 不是...而是... denies one reading and supplies the correction.
不是贵,而是远 = not expensive, but far.
bú shì guì, ér shì yuǎn
