Hi Sandra,

Just some suggestions for your writing: 

(1) We use the linking verb "is" to link an adjective (multi-cultural) to the pronoun (It). We use "has" to describe a possession or having a quality. 

Examples:

Dominic has great wealth. (Dominic possesses/owns a lot of assets.)

Dominic is wealthy. (The adjective "wealthy" describes "Dominic".)

(2) We need the apostrophe ('s) to mean "Chinese society". 

Another example: 

This painting, just like his, is impressive. 

This painting, just like Derrick's, is impressive. 

(3) We can use the word "erosion" to describe the loss of a culture with time. 

(4) When the subject of a sentence is doing more than one thing, we do not separate them with a comma.

Example: Tim will sing, and play the saxophone. (incorrect) / Tim and sing and play the saxophone. (correct)
