Ni Guangnan applied for Lenovo Hanka patent.

Because with the passage of time, academics are progressing, and then Academician Ni Guangnan studied Hanka when he was a student. In fact, related academic things have made great progress, but he may not have so much time to study, so he didn't keep up with the trend of academic progress. He feels that his academic level should reach such a high level. Perhaps his so-called academic retrogression is to retreat if you don't advance in the current environment.

Ni Guangnan, an academician of China Academy of Engineering, pioneered the application of Lenovo function in Chinese character input during his tenure in Computing Company of China Academy of Sciences (predecessor of Lenovo Group) and the first chief engineer of Lenovo Group, and presided over the development of Lenovo Chinese character system and Lenovo series microcomputer. Hanka is a product of a specific historical period, and it is an effective means to solve Chinese character information processing in the period of low performance of microcomputer software and hardware.

At that time, when those western computers were introduced into China, there was no so-called Chinese input method. They all input English characters, so in order to convert English characters, some scientists in our country have studied Hanka, so its main function is to input Chinese characters into computers with English characters as the main characters. At that time, the computer system with English characters as the language had developed very well. If we abandon this kind of microcomputer that they do well and study computers with Chinese characters as the main language, it will be a bit far away.

So the best way is to study a language converter, which is what Academician Ni Guangnan said. We would rather not make a complete microcomputer system, but make a component-"Hanka" inserted in PC. From the academic point of view, this seems to be a retrogression, but from the market point of view, this is a great progress.
