The art education in China emphasizes the training in basic skills. I was in an art supply store, and this photo showing the section of casts for drawing. In art schools, students spend significant amount of time doing cast drawing to develop the sensitivity of observations, obtain thorough understanding of perspectives and anatomy. This rigorous training lays a solid foundation for these artists. They have a plenty of tools handy for their creative processes. So it is not surprising that so many wonderful representational artists coming from this part of the world.
