Written Chinese
Because the majority of modern Chinese words contain more than one character, there are at least two measuring sticks for Chinese literacy: the number of characters known, and the number of words known. John DeFrancis, in the introduction to his "Advanced Chinese Reader", estimates that a typical Chinese college graduate recognizes 4,000 to 5,000 characters, and 40,000 to 60,000 words. Jerry Norman, in "Chinese", places the number of characters somewhat lower, at 3,000 to 4,000. These counts are complicated by the tangled development of Chinese characters. In many cases, a single character came to be written in multiple ways. This development was restrained to an extent by the standardization of the seal script during the Qin dynasty, but soon started again. Although the "Shuowen Jiezi" lists 10,516 characters—9,353 of them unique (some of which may already have been out of use by the time it was compiled) plus 1,163 graphic variants—the "Jiyun" of the Northern Song Dynasty, compiled less than a thousand years later in 1039, contains 53,525 characters, most of them graphic variants.
Simplified Chinese characters
There had been simplification initiatives aimed at eradicating characters entirely and establishing the Hanyu Pinyin romanization as the official written system of the PRC, but the reform never gained quite as much popularity as the leftists had hoped. After the retraction of the second round of simplification, the PRC stated that it wished to keep Chinese orthography stable. Years later in 2009, the Chinese government released a major revision list which included 8,300 characters. No new simplifications were introduced. However, six characters previously listed as "traditional" characters that have been simplified, as well as 51 other "variant" characters, were restored to the standard list. In addition, orthographies (e.g., stroke shape) for 44 characters were proposed to be modified slightly to fit traditional calligraphic rules. Also, the practice of unrestricted simplification of rare and archaic characters by analogy using simplified radicals or components is now discouraged. A State Language Commission official cited "oversimplification" as the reason for restoring some characters. The language authority declared an open comment period until August 31, 2009 for feedback from the public. The proposed orthographic changes to 44 characters were not implemented due to overwhelmingly negative public opinion.
