1. In Chinese, the use of quantifiers is very important, because different nouns need different quantifiers. Quantifiers can be divided into two categories: general quantifiers and specific quantifiers. The universal quantifier is a quantifier suitable for many nouns, such as "ge", "Jian" and "Ben". Specific quantifiers are only applicable to a certain kind of nouns, such as "branch", "root" and "Zhang".
2. When using quantifiers, it should be noted that different nouns need to be matched with different quantifiers and cannot be confused. For example, "a book" is the right collocation, while "a table" is the wrong collocation.
3. Some nouns have specific quantifiers, such as "a cat" and "three birds". These nouns don't need to add general quantifiers. In some special cases, some special quantifiers can be used to express uncertain quantities, such as "some", "several" and "a little".
