The original idea of the father of Sogou Pinyin Input Method was for Baidu.

In June, two years ago, Ma ZhanKai, who was 23 years old, made an important decision in his life to abandon his job in a state-owned enterprise in Taiyuan. Although he did not understand the technology at that time, he liked to surf the Internet and search for all kinds of contents. He found that many characters were difficult to type in the current input method, such as "Zhou Jielun" and "Titanic". From this point, he increasingly believed that the high-frequency vocabulary of the news which netizens usually searched should be added into the input method, so he came up with the idea of search input method.
