In the development process of Chinese character,seeking to be different in
the form of Chinese character sometimes is consistent
with the law,sometimes inconsistent.Those consistent with the law aim at solving the problem caused by the fact that a form is shared by more than one word,thus a new form is invented so that the meaning of each word can be clearly expressed with a typical form.Those
inconsistent with the law are caused by the fact that sometimes the rulers or other social individuals subjectively invented a new form for the existing word in order to meet their certain need,and sometimes the social individuals might invent a new form for the existing word because of their different understanding toward certain thing.Whether it is consistent with the law or not,the choice of each form has its ground under that social circumstance,and the form either has its value in the study of Chinese characters or has its value in the study of social culture,so it conforms with the inevitable choice of human's thinking principle.
