Thanks for taking the time to explain the characters. You taught me four new characters today, as 人 is seen quite often on my online course in Mandarin. The biggest problem is the pronunciation, since, for example, rén sounds like jeune (young) in French. Maybe you can help me on Skype with the pronunciations of  characters like  见, 想,etc.
