Abstract: The set of Chinese characters which is easily confused is one of the important sources during the process of identifying wrongly written characters．In the study, firstly we sorted out 11935 possibly-wrongly written characters by hand．Then taking those characters as nodes and "possibly-wrongly written characters" relations as sections, we constructed the set of wrongly written characters which is easily confused into a diagram．Due to the great limitation of manually sorting out wrongly written characters, on the basis of the diagram, we designed the internal-expanding algorithm that expands the set of wrongly written characters and the open source data external-supplementing algorithm that supplements the set of wrongly written characters through large quantity of corpus．In that way, we would expand the diagram and new pairs of wrongly written characters．According to the experiment, we newly found 15133 groups of wrongly written characters pairs．After proofreading samples at random, accuracy reachs 87.35%.
