By 2R, we mean the Radicals and Roman spelling of Chinese language. They form a high barrier between man and machine that makes use of the 2R. A system has been developed by recognizing the four basic patterns (4BP) of Chinese characters. With the 4BP, we can build character codes and word codes of Chinese language. Since the 4BP (squares, horizontal, vertical and miscellaneous [non-straight] strokes) can be recognized easily by anyone, be Chinese or non-Chinese, there would be no barrier between man and machine that makes use of the 4BP codes. By such means, Chinese culture could be extended to every corner of the world in a not distant future.
