You might have noticed some Chinese people have trouble using the plural form of English nouns. This is because Chinese grammar is different; nouns in the Chinese language never change form. Here are the most common ways on how to use plurals in Chinese, to denote two or more of something.

1. Add "們" to indicate a plural

Use 們 (men) after pronouns or nouns that refer to people.

Examples:

Pronouns：你們，我們，他們，她們
Other nouns：老師們，學(xué)生們，老人們，媽媽們

However, there are some exceptions:

(1) "您們" and "誰們" are not correct. There is still controversy about "您們". It's better not to use it.

(2) When preceded by numbers, nouns cannot be followed by 們
五個學(xué)生們 (? WRONG)

(3) 們 can be used in the personification of something non-human e.g. animals or plants.
小狗們喜歡玩游戲。 (Xiǎo gǒu men zuì xǐ huan wán yóu xì – Puppies like playing games.)
花兒們在風(fēng)中跳舞。 (Huār men zài fēng zhōng tiào wǔ – Flowers are dancing in the wind.)

2. Use a measure word to indicate a plural

Below are three situations where the number + measure word + noun structure is used for plurals in Chinese.

(1) More than one of a noun

Any time you know the quantity of a noun and the quantity is more than one you can use this structure: Number (>1) + normal measure word + noun.

Examples:

三只狗 (sān zhī gǒu – Three dogs)
五個杯子 (wǔ gè bēi zi – Five cups)
六杯啤酒 (liù bēi pí jiǔ – Six glasses of beer)

(2) A special quantity of a noun

Sometimes you might need to refer to one of a special quantity of a noun (ie. pairs, dozens, several, batch, etc.). In these cases, you can use a special measure word. These are some special measure words, which can denote a defined or undefined quantity that follows this structure: 一 + special measure word + noun

Examples:

一雙 yī shuāng / 一對 yī duì – pair 一雙手 (yī shuāng shǒu – A pair of hands)
一對花瓶 (yī duì huā píng – A pair of vases)

一些 yī xiē – several
一些書 (yī xiē shū – Several books)

一打 yī dá – dozen
一打啤酒 (yī dá pí jiǔ – A dozen of beer)

一批 yī pī – batch
一批貨物 (yī pī huò wù – A batch of goods)

一群 yī qún – group
一群鴨子 (yī qún yā zi – A group of ducks)

(3) An ambiguous quantity

If you don't know the specific quantity, you can use ambiguous number words. When using an ambiguous number follow the following structure: ambiguous number word + measure word + noun.

Examples:

幾 (jǐ – Several)
幾家很好的飯店 (jǐ jiā hěn hǎo chī de fàn diàn – Several good restaurants)
很多 (hěn duō – Many, a lot)
很多（間）教室 (hěn duō (jiān) jiào shì – Many classrooms)
不少 (bù shǎo – Many, not few)
不少學(xué)生 (bù shǎo xué sheng – Many students)
數(shù) (shù – Several)
數(shù)月不見 (shù yuè bù jiàn – Haven't met for several months)
