Chinese Language for Teens and Adults
Teens and adults learn differently from kids. They understand that language has structures and note correct grammar and syntax. Thus, it is actually easier for them to understand how to learn a language. What gives kids an edge over their older peers is in imitating accents?
However, there have been many adults asking for Learning Chinese. Many adults want to study Chinese for business, travel. And some older people want to study Chinese to exercise their brain.
It would be ridiculous to say that adults aren't capable of learning Chinese. With enough practice, anyone can become a master at the language!
