Question

What is the plural possessive form of Chinese?

Answer 1

Hint: Chinese nouns may be counted or uncounted. The plural form will also be Chinese in more general, widely used contexts. However, in more specific ways, such as when referring to different forms of Chinese or a selection of Chinese, the plural form may also be Chinese.

Complete answer:
Plural possessive - A noun is plural when there are more than one of it. The majority of nouns are made plural by adding a "s" to the end, but there are exceptions, as with so many items in the English language (e.g., tooth and teeth). When a noun displays ownership or possession of something, it is said to be possessive.

Plural possessives display possession of something when there are several instances of a noun. Most plural nouns' possessives are formed solely by adding an apostrophe:
Sonali had two Puppies. When they were playing in the hall, the Puppies' toy went under the sofa.
So, The word "Chinese" cannot be used in a plural or possessive.

Explanation –
The adjective "Chinese" is a noun. It is used to classify nouns.
"I like Chinese food," you might tell.
"Chinese went to the supermarket," you can't tell.
It isn't self-contained. Adjectives must be used to define a word.
It would make sense to say, "A Chinese individual went to the shop."
"Chinese people's cookies taste wonderful," you might say to make your word plural and possessive.

Note: The possessive of plural nouns that do not end in "s" is an exception to this rule. An apostrophe and a "s" are added to the noun to form these:
The women's dressing room was very beautiful.

It's also often a good idea to rephrase a sentence to avoid using uncomfortable plural possessives. There is no hard and fast rule here, and both phrasings are right, so use whichever one sounds best to you.
To find out, read your sentence aloud and listen to see if the plural possessive sounds uncomfortable. "The Rodgerses' house is huge," for example, is a mouthful, so you may want to change it to "The Rodgers family has a big house."
