According to the morphological information of Chinese characters, each word or word is given a code, which is called the font code of Chinese characters. Zheng code is a form code, and the basic principle of its coding method is:
Square Chinese characters are regarded as a combination of word-formation units, the basic word-formation unit is root, and the smallest word-formation unit is stroke.
For example, the four radicals of "root, meaning, redundancy and mouth" can be combined into three radicals of "crucian carp and crucian carp", and "eye, moon" and "strokes" can be combined into two words of "miscellaneous and point".
The order of radical arrangement is called radical order, which is consistent with the writing order.
According to the reverse process, Chinese characters can be decomposed into roots and strokes, and then substituted into the codes of roots and strokes, and the codes of Chinese characters can be obtained. Input the code into the computer, and store the Chinese character information in the computer through internal code conversion.
For example:
Crucian carp-fish \ R gen \ X \ Y-RXY
Electricity-Guangdong \ K \ Z-KZ
Zheng Ma established the retrieval order of "strokes-roots-whole words-words" by using font information coding. In other words, hundreds of radicals are derived from several strokes, tens of thousands of Chinese characters are derived from hundreds of radicals, and tens of thousands of words are derived from tens of thousands of Chinese characters.
In order to meet the needs of different users, Zheng code input method is divided into two types: popular and standard. The "standard" duplicate code rate is low, suitable for high-speed blind typing. It is not only suitable for the input of 6763 Chinese characters in the current universal character set, but also can conveniently input 20902 Chinese characters with large character set in WINDOWS 98 with the same coding rules. The universal coding rules are simple and easy to learn, but they cannot be used to input Chinese characters with large character sets. "Ordinary type" can be used as the learning ladder of "standard type", because the codes of both radicals are * * *, so you can naturally transition to "standard type" after you are proficient in using them.

Report to the authorities
Compared with, Zheng Codex came out earlier. Whether it is good or bad has its advantages and disadvantages. Zheng code is a little more standardized, but the roots are obviously more than that. Typing with Zheng code is more painful and unnatural. However, Zheng code also lost its identification code.
In the national standard range, Wu Bi's duplicate code is less than the direct ratio. In and beyond places, Zheng code is less duplicated, so Zheng code is suitable for people who specialize in inputting ancient Chinese, while it is more suitable for ordinary workers.
The history of Zheng Ma
If we say that the most popular Chinese stroke input method (character code) in the world is definitely not a five-stroke font, but a A Zheng code.
For most people, Zheng code is the most familiar and unfamiliar input method. Is the only pre-installed stroke input method in windows system. Except Zheng code, all other spelling codes, Microsoft Pinyin, Smart ABC, etc. They are all pinyin codes. However, I have used the computer 10 for many years, and I have never met anyone who can use Zheng Ma.
Since windows95, all Chinese windows systems (95/98/NT/2000/XP) are pre-installed. Why on earth is this? Who invented Zheng Ma? Why did Microsoft choose positive codes instead of fonts? Is there really anything special about Ma Zheng?
Who invented Zheng Ma?
The inventor of Zheng Ma is Professor Zheng Yili, a famous linguist in China and the editor-in-chief of Huaying Dictionary, which is well-known at home and abroad. I happen to have this dictionary compiled by him at home, version 1965, printed in type, and now it is old. Therefore, I feel very cordial about his name.
The origin of Zheng code and font
Professor Zheng Yili has been studying the scheme of Chinese character splitting for decades. 1980, he completed the world's first "26-key Chinese character radical input code scheme" for inputting Chinese characters into a computer by using only 26 English letter keys of a general keyboard. However, he selflessly taught Wang Yongmin and others his years of research experience and inventions of radical and Chinese character coding theory and scheme. Wang Yongmin and others completed the invention of fonts on the basis of Zheng's research. It can be said that, if it weren't for his selfless dedication at that time, the stroke input method, which is now dominant in China, would never be a five-stroke font. Although Wu Bi achieved great success and honor after his birth, Zheng Yili still felt that Wu Bi's division of Chinese characters was not very reasonable and perfect, especially it did not conform to the norms of Chinese characters, so he continued to study and improve it. With the help of his daughter Zheng Long, * * * finally invented a more standardized and perfect Chinese character stroke input method-"radical universal code". That is, the Zheng code that we later saw.
Zheng Ma's Excellence
Ma Zheng is based on single word input and mainly on text input. With 2-4 English letters, you can enter 2 words, multiple words and phrases within 30 words. Under this mixed word input, the average code length of a Chinese character is between 1.8- 1.9 keys. He has two dictionaries, which contain 25,000 and 50,000 words respectively. In order to meet the needs of different users, Zheng code input method is divided into "popular" and "standard". The "standard" duplicate code rate is low, suitable for high-speed blind typing.
Zheng Ma's advantage is that Chinese characters are in line with the national language and writing norms, standardized, easy to learn, fast and universal (of course, this is easy to learn and fast, relative to the stroke input method at that time), which can be popularized and applied in primary and secondary schools and society. Zheng Ma has won many national awards and honors. (Now it seems that the fastest Chinese input speed should be Wu Bi font, which has exceeded 300 words per minute. The maximum speed of Zheng code is about 240 words. The easiest input method to learn, I think, is Pinyin: d)
However, Zheng code has an important advantage that other input methods cannot replace: it can easily encode 654.38+10,000 Chinese characters without changing the coding rules and radical codes. In other words, learn to use Zheng Ma to input thousands of commonly used Chinese characters and code them in the same way. You can also input tens of thousands of China uncommon Chinese characters and Japanese and Korean Chinese characters. With Zheng code, we can easily input Chinese characters of China, Japan and Korea, and we can also input Chinese characters with super-large character sets, such as Shuo Wen Jie Zi and Kangxi Dictionary, which are unmatched by other input methods.
At the end of 1994, Samsung was entrusted by the Korean government to introduce Chinese character input method into Chinese mainland, so as to complete the Korean Chinese training system and the electronization of the Korean tripitaka, a precious national treasure with more than 50 million Chinese characters (in fact, this tripitaka was also introduced from China by the Korean dynasty in the Northern Song Dynasty). China Information Society recommended more than a dozen input methods to South Korea. Soon Samsung sent three experts. With the cooperation of China Information Society, these dozens of "codes" were inspected, tested and screened in turn. After rigorous testing and assessment, the company's top management finally decided to choose three "codes" (input methods), and now it is decided to choose only one, that is, Zheng code. In conclusion, the chairman of South Korea's Samsung Group said: "Ma is the most successful technology introduction of Samsung in 1995."
The origin of Ma Zhenghe's window
After a series of national tests, evaluations and reviews, Ma Zheng is considered to be the world's leading level. The Chinese character coding system honed in this way can be finalized and popularized. Zheng Yili suggested that Zhong Yi Company, which took over his baton, aim at a new target-curve Chinese character library. Because this is another key factor that we can't care about except the operating system in Chinese information processing.
Chinese character library is the final form of Chinese information processing, because what you see is neither input method nor operating system; This is an article printed in exquisite Chinese characters. The primary stage of computer Chinese character library is a Chinese character font composed of various "dots" Describe Chinese characters as "dots". You can't zoom in and out indefinitely, it should be the size of a semicolon like type, and the slightly larger dot matrix words and strokes are ugly like sawtooth edges. At that time, the Chinese character library on the general typesetting system was a vector Chinese character library with medium technical level. That is, a straight line is used to describe the font of Chinese characters. Needless to say, the straight part consists of many broken lines. This kind of Chinese character library, if enlarged slightly, will be deformed because of the broken line of the curve part and cannot be used. Zhong Yi Company wants to enter the field of Chinese character library development, and is determined to surpass vector Chinese character library and catch up with the world's most advanced technology of describing Chinese character library with curves. At that time, only 2-3 companies in the United States had the technology of describing western languages with curves, and it was much more complicated to describe Chinese characters with curves than western languages. The company made use of the few curve description fonts in the world to disclose data, organized software engineers to tackle key problems in the depth field of curve fonts, hired the most authoritative font expert in China as the font technical director, and cooperated with China Standard Technology Development Company to develop national standard dot matrix fonts, thus launching a campaign to reach the highest international level and connect with international curve standards!
Making curved Chinese fonts is a project with long period, high technical level, high risk and large capital investment. Zhong Yi Company has been operating continuously for four years, and has basically improved Ma Zheng, without any income. When they seek cooperation from some large computer companies in order to seek funds for developing the curve Chinese character library, they think that the application opportunity of the curve Chinese character library of 20,902 Chinese characters that meets international standards is still far away. It is too risky to invest a lot of money in development now, for fear that it will not pay off, so everyone politely declined.
However, Zhong Yi believes that in the information age, the technological update is not coming gradually, but like a triple jump. As China people, we should lead the world not only in Chinese character input method, but also in the field of Chinese character library technology, so as to be worthy of being the ancestors who invented Chinese characters and talked about calligraphy art!
As expected, at the beginning of 1994, Microsoft, the world's largest American company, was ready to abandon the Chinese version of Windows3.2, which had just been launched for a few months, and fully develop the Chinese version of the 32-bit operating system Windows 95. Including 20902 Chinese characters in China, Japan and Korea. Engineers from Microsoft Corporation of the United States will soon come to Beijing to investigate who owns the Chinese character library of 20,902 international standards. Which input method can support (retrieve) these 20902 Chinese characters? They immediately found the Zhong Yi company. When they learned whether Ma Zheng could support (retrieve) 20,902 international standard Chinese characters, Zhong Yi Company showed them the input (retrieval) of 60,000 computer Chinese character libraries in the world at that time. When they saw that Zheng Ma could quickly and accurately input 60,000 Chinese characters with only four keys, they were extremely surprised, which was beyond words. Even if all 60,000 characters are entered so neatly, there are still 20,902 Chinese characters in the air. When asked who owns the 20,902 curve Chinese character library, Zhong Yi Company easily showed them a complete set of printed samples. In the next half month, they sent engineers and management experts of different levels to Zhong Yi Company for consultation and investigation four times. After confirming that everything was complete and correct, they asked for samples and left with satisfaction.
Since then, with the promotion of the Chinese version of Windows, Ma Zheng and Zhong Yi fonts have entered the computers of millions of China users.
