In 1926, Mr Hu Shi, who had a thorough knowledge of both western and Chinese learning and was awarded 26 PhD titles, said that arranging Chinese characters is the most difficult thing, but on the other hand it has to be done. Firstly, classifying and ordering Chinese characters … … the sequence of Chinese characters is the basis of all kinds of indexes. The difficulties mentioned above arise from the fact that Chinesecharacters are unordered. Neither of precedent nor present methods that trying to order Chinese characters by radical, Pinyin, number or stroke, cannot make the breakthrough. One of the core technology of numerical Wangma ‘first and remaining radical’ coding method, could digitalize the Chinese character graph in one step. It is not only an easy-learning input method, but also an easy-learning ordering method featuring good uniqueness. This technology makes Chinese character input method compatible with dictionary lookup method, and gives Chinese characters a ‘readable numeric sequence’. This is ‘The theory of Chinese character sequence’.
