No "words" section to review vocabulary in Chinese.
Why isn't there a "Words" section in Chinese like there is in Italian. It would be useful to review Chinese symbols, the PinYin form, and the definition in a single place within Duolingo to help strengthen comprehension.
This is something that needs to be looked at as I feel this course is lacking without it. I am left feeling like I learned nothing after each exercise. Whereas in Italian for example there was a sense of accomplishment and understanding after completing every section.
