Answer:
The complete subject is the NP "the Chinese New Year" and the predicate is the VP "is an important traditional holiday in China".
Explanation:
The subject of the sentence is the person or thing that is doing an action, or the person or thing that is the focus of the sentence. On the other hand, the predicate is everything that is not the subject, it generally contains the action. It includes all the description of the action and the objects that are affected by the action.
