Duì 对/對 ‘toward, to’ is a preposition indicating to whom an action is performed or a target of an action. It can also occur in constructions indicating an attitude towards someone or something. Together with a noun or pronoun, it forms a prepositional phrase that introduces the object.

Negation
1. In sentences with a verb expressing an action as a predicate, the negation is usually formed by adding negation adverb bù 不 or méi yǒu 没有/沒有 before the prepositional phrase with duì 对/對.
The negation adverb is usually placed before the verbal predicate in sentences with the preposition duì 对/對 used to indicate an attitude toward someone or something.
2. The negation of sentences with yǒu 有 as predicate is formed by placing the negation adverb méi 没/沒 before yǒu 有.
3. The negation of sentences with adjectives as predicates usually needs to be placed before an adjective.
With adverbs
1. In sentences with verbs describing actions as a predicate, adverbs such as dōu 都 ‘all’, yě 也 ‘also’, chángcháng 常常 ‘often’, yòu 又 ‘again’, yǐjīng 已经/已經 ‘already’ usually need to be placed before the prepositional phrase with duì 对/對.
2. In sentences expressing an attitude with a verb as predicate, adverbs such as dōu 都 ‘all’, yě 也 ‘also’ usually need to be placed before the prepositional phrase with duì 对/對.
Alternatively, adverbs such as dōu 都 ‘all’ and yě 也 ‘also’ can be placed after the prepositional phrase with duì 对/對.
3. In sentences expressing an attitude with the verb yǒu 有 ‘to have’ as predicate, adverbs such as dōu 都 ‘all’, yě 也 ‘also’, yòu 又 ‘again’ can be placed before the prepositional phrase with duì 对/對.
Alternatively, adverbs such as dōu 都 ‘all’ and yě 也 ‘also’ can be placed after the prepositional phrase with duì 对/對. In such a construction, the emphasis is put on the noun or pronoun which follows the preposition duì 对/對.
4. In sentences expressing an attitude with adjectives as predicates, adverbs such as dōu 都 ‘all’, yě 也 ‘also’ can be placed before the prepositional phrase with duì 对/對 or before the adjective.
