Regardless of how early the text of the "Analects" existed, most "Analects" scholars believe that by the early Han dynasty (206 BC–220 AD) the book was widely known and transmitted throughout China in a mostly complete form, and that the book acquired its final, complete form during the Han dynasty. However, Han dynasty writer Wang Chong claimed that all copies of the "Analects" that existed during the Han dynasty were incomplete and formed only a part of a much larger work. This is supported by the fact that a larger collection of Confucius's teachings did exist in the Warring States period than has been preserved directly in the "Analects": 75% of Confucius's sayings cited by his second-generation student, Mencius, do not exist in the received text of the "Analects".
