Being a beginner, of course I am bit puzzled by the concept of "shì" being used not for describing nouns with adjectives.
Using search, I think it is clear to me that:
- Noun + noun = I can use "shì".
- Adjective + noun = I should use "hen".
Well but what I am unable to figure out is the combination, like "This is my new phone". I am connecting two nouns, but also connecting an adjective and a noun. What rule is the applied?
