Pay attention to the following points when using quantifiers:
1. If quantifiers are temporary noun quantifiers, it is generally easy to insert adjectives. He ate a big bowl of rice in the evening.
2. If the quantifier is a special noun quantifier, there are many restrictions, so it should be used with caution. He is carrying a large piece of luggage.
3. There are limited adjectives that can be inserted, mainly a few monosyllabic adjectives such as "big, small, thick, thin and long".
