Many of the Chinese terms for chemical elements used are made from John Fryer and Xu Shou in 1872. They use the syllable of chemical elements to prefix the Chinese radical according to the characteristic of each element. Each element is phonetic and represented by a character. The new characters conflict with •the principle of xingsheng (combination of a graphic and phonetic element). The Chinese consider them a matter of foreigner intervention during the 19^(th) century. To Fryer there was special reason for the unique translation. In order to avoid the effect of "xixue zhongyuan" (the western science derived from Chinese) Fryer invented the new characters. He realized that the new characters may have other problems, because the Chinese do not understand them.
