Mongodb database (newbie) problem

Question

The requirement is: when the number of comments on an article changes, the cNumber in the article also changes. Can this be achieved by designing a Schema? Articles and comments are two Schema (new to mongodb, sorry for the inaccurate question)

It’s a database design problem. Shouldn’t cNumber read the number of comments? It doesn’t need to be stored in the article.
