Korean Characters have positive and negative transfers to acquisition of Chinese Characters. Positive transfers are presented by that it is easy for Korean students to grasp Chinese character integrity, Chinese character stroke centrality as well as stroke order. The negative transfers concentrate in errors of the shapes, the relations of Chinese character strokes. The errors of the shapes of Chinese character strokes include: missing or changing the hooks in hook strokes into other different angles; changing dot strokes into vertical, horizontal, or left-falling ones; changing left-falling strokes into vertical, horizontal, or dot ones; changing horizontal strokes into left-falling ones and so on. The errors of the relations of Chinese character strokes include: confusing crossing strokes with joining ones, longer strokes with shorter ones, inside strokes with outside ones. These errors are not only related to Korean Characters and Chinese Characters in Korean, but also related to features of Chinese Characters, entirety priority of visual process and the attitudes of learners. And more attention should be paid to that these errors especially hook strokes errors are systematic and rational.
