in terms of means concerning or with regard/reference to your essay is the best in terms of grammar and spelling.

chinese is really difficult to learn, especially in terms of reading comprehension

I am going to write a book in terms of Chinese culture.

I believe it is the same as 關於/對於。 in terms of effectively means 'with regards to'. "in terms of" is a bit easier to say in spoken english - it doesn't sound so formal like "concerning ___" would. so you can use it pretty generically, here is a contrived example: A: "How does he look?" B: "In terms of his face or his clothes?"

Example of the usage "in terms of" 1. As a synonym it means: measured or indicated by; in units of: distances expressed in terms of kilometers as well as miles; cheap entertainment, but costly in terms of time wasted. 2. In relation to; with reference to: "facilities planned and programmed in terms of their interrelationships, instead of evolving haphazardly" (Wharton Magazine).
