Recently with a friend who study abroad discuss drawing, he is a very famous art college in the United States, and he gives me deep feelings of communication, now the domestic and foreign well-known art college teaching of art college, is not "what", but in "how to learn", their learning methods and process is superior to domestic, a question to professor lecturing, group discussion and in-depth research, access to a large number of literature data, visit the higher-ups, writing papers, and so on, very solid understand the question, is more of a domestic teaching, homework that is all, the problem can't deeply understand, like this was supposed to have a vibrant green eye, was dry "moss" is full, can not get the necessary nutrients, will more walk more narrow.
