"Why do you look so confused?"
Cheng Yang asked Mo Roulan who said immediately
"Because I don't understand what you are talking about? How can Chenchen know these languages? The school in the town we studied in …they didn't use to teach any language other than Chinese and even in this school, they don't teach these languages."
Only expensive schools taught these languages. Unfortunately, Mo Roulan and her mother couldn't afford to send Mo Chen to such schools.
While Cheng Yang looked completely confused by what Mo Roulan said.
"But I saw so many books in his room….most of them are in different- different languages. There is some library stamp on them so I think he brought them from the school library. I don't think that he just brought them because he was curious as all of them seemed to have some pencil marks. I mean some important formulas of physics…are marked. "
