I lived and worked in China for 11 years, and am currently Level 4 out of 6 on the HSK scale (Chinese Proficiency Test) and improving. My last job in China was teaching computer animation, for which I had to do all the classwork in Chinese. Before that I was a translator and editor for a Chinese government agency.
That pretty much says enough, I hope, for the time being.
