How do you go about defining and analyzing illiteracy?

1) "Man" means "tattoo". "Illiteracy" means "tattoo blindness". It refers to a person who does not know how to write.

2)A person who recognizes words but lacks the ability to think.

3)A person who recognizes the written word but does not understand the specific language and culture.

For some pinyin scripts, as long as one understands the minimum rules of pronunciation, one can read the pronunciation and then understand the meaning of the text through speech. Therefore, there are few illiterate people in the countries with pinyin characters

For ideographs, such as Chinese characters, it is easy to understand the meaning but not know the pronunciation, or know the pronunciation but not know the characters, and without specialized learning of language, illiteracy is bound to occur.

Modern society, illiteracy does not only mean "illiterate people", with the advent of the knowledge-based economy, there may be people in the lack of knowledge of a particular aspect of the new illiteracy. People who do not know how to use foreign languages or computers may become "illiterate". The purpose of "literacy" is not simply to enable an illiterate person to recognize a few words, but to enable him or her to understand culture better, to cultivate himself or herself, and to acquire the practical knowledge and skills needed for a better life.

Many illiterate people who can read nowadays refer to functional illiteracy

The so-called "functional illiteracy", proposed by the United Nations at an international conference in Tehran in 1965, refers to people who have had some traditional education and can do basic reading, writing and arithmetic, but are unable to recognize the symbols and charts of modern information and cannot make use of the facilities of modern life. People who are unable to utilize modern living facilities.

Functional illiteracy is relative to traditional illiteracy, which refers to people with a very low level of literacy, or, to put it bluntly, people who have not studied. But nowadays society is developing too fast, new things are constantly applied to our lives, because some people for various reasons (no opportunity or psychological resistance) did not contact these things, over time, they are not very adaptable to this society, we become what we call functional illiteracy.

Functional illiteracy, different from the traditional illiterate "illiterate", although they are well educated, but in modern science and technology general knowledge, but often as "illiterate" as poor, especially with the arrival of the knowledge-based economy, a variety of rich in science and technology content of new products pouring in. Especially with the advent of knowledge-based economy and the influx of new products with scientific and technological content into daily life, there will be more and more of these "functional illiterates". For example, although computers have become more and more popular, but some professors of liberal arts in the university may not even understand the computer, because of this, many educationalists have put forward the concept of "lifelong education".
