Cheer Up Your Day and Learn Chinese

I studied in Chinese School before. After PMR, I decided to drop Mandarin subject. The single most regretful thing I've done in my life. I am thinking of reviving my Mandarin skill whenever time permits me, which evidently doubtful with the fact that I'm in medical line, now about to enter clinical years. My friend showed me this but stupidly I thought it was a quick way to re-spawn a bit of my Mandarin. You'll be surprised at how good you are at Mandarin. hehe..
