Chinese adjective order

First of all, the use of adjectives is influenced by the number of syllables of nouns they modify. Generally, disyllabic adjectives modify disyllabic nouns and monosyllabic adjectives modify monosyllabic nouns. For example, a beautiful girl can not be called a beautiful person, but can be called a beauty. This is the general situation, not absolute.

Second, adjectives with "de" usually come first. As you said, "China is the best" and "immigrant" city, but the other way around.

In addition, the modifiers of subject-predicate structure must take "de", such as "I said" and "he wrote". Generally, it will be put in front of other structures, such as "what he wrote in calligraphy".

Thirdly, adjectives that are closer to nouns are closer to nouns, especially some unchangeable attributes, such as gender, color, constituent materials and so on. Moreover, such words generally do not have "virtue", such as "silk skirt" and "female teacher".

Fourth, the positions of quantifiers and demonstrative pronouns are flexible, but sometimes different positions will cause ambiguity, which is the example you gave. Changing the location will turn "Shanghai" into "the best", which is not in line with the original intention, just like the second floor said. If there is no ambiguity, you can change places.

Personally, the above can explain the arrangement of adjectives in many cases, such as "his favorite beautiful white sweatshirt" and "his favorite beautiful white sweatshirt".

I hope it can inspire you.
