The so-called technique is the author's approach to image and space in woodcarving creation. This technique is mainly embodied in the sense of reduction of sculpture and carving, to be exact, from the outside to the inside, step by step by step by subtracting waste, gradually revealing the body excavation. In the subtraction modeling, we not only feel the pleasure of "shelling out" of the work. Even though it is thrilling because of the characteristics of wood or the fact that too much effort will reduce the place that should not be subtracted, if properly handled, it may also be delighted by the dangers. At the same time, we can also feel the special charm produced in the process of using various knife techniques, some accidental effects, which can make the works produce new charm. Therefore, in the creation of woodcarving art, it is a complex and meaningful process with changeable psychology. The formation of beautiful knife method is the expression of skilled technology. Often, when someone copies a good picture, the most difficult thing is the brush strokes, because the brush strokes are the product of the author's mind and skills, so is the knife method, which is difficult to embody in any imitation. Therefore, only by mastering skills and constantly accumulating experience, can we achieve the ideal knife method of our own. That kind of wood grain and sculpture, smooth and rough, concave and convex, circular knife arrangement, flat knife cutting... The charm of the artistic language they express is beyond the reach of other sculptures.
