Michael Jackson's song Who Is Bad still can trigger my best memories of my 1990's college time. There was once a saying about Michael. There were two types of musicians in the world, one is Michael Jackson and the other one is the rest of musicians in the world. I like this one. I still admire his genius in dancing and singing and its perfect integration of the two.

Who Is Bad is one of the classics of him. In photo to painting business, who is bad? Is the price leader bad? Or the printing and then painting vendors who still join the team to sell low quality and low skilled painting of portraits and paintings? In fact the market always allows the co-existing of good and bad. It is our constant task to bang on the bad ones in order to be more outstanding. If the market is only full of good ones, the relatively worst ones still are the spurs to the best ones.
