I studied master's and doctoral courses in electronic information and communication at Waseda University. And obtained the master's degree and doctor's degree in 1994 and 2000 respectively. 12 years, in Japan, in addition to learning the standardization of Chinese characters and symbols, I also learned a lot of information processing technologies.
