In simple words, this course is useless for those who don't get chinese. Most part of the videos are in chinese for which english subtitles are not available. If you are doing this course on coursera, congratulations!!! You are wasting your time, money and efforts. I am regretting so much after taking this course. I don't understand more than half of the materials. Coursera just looted you by telling that this course is in english but in reality major part is in chinese with no english subtitle. I hate this course and I want to file an official complaint because of its poor quality.
