Negation of "you" with "mei"

The verb 有 (yǒu) is negated differently from ordinary verbs. Rather than putting 不 (bù) before it, you put 没 (méi) before it.

Structure

Nearly all verbs can be negated with 不 (bù). The verb 有 (yǒu) is an exception, and must be negated with 没 (méi).

Subject + 没 + 有 + Object

Never use 不 with 有.
