However, his work on Tsang-chieh did not begin until he worked at "Cultural Abril", a publishing house in Brazil, in 1972. From then on, he would dedicate his life to modernizing Chinese information technology. He saw for himself how the Brazilians could, in just one day, translate and publish foreign literature, while the Chinese took at least a year. The technology then, coupled with the complexities of the Chinese script, required a painstaking process of picking up type pieces from an enormous Chinese character set. Besides, publishers often encountered characters not included in their set. This meant that the printing of any information in Chinese was much slower than in other languages. In 1973, he returned to Taiwan. He gathered a team to study an efficient method of looking up a character with 26 keys on the common keyboard.
