In Chinese book history

the period from the primitive books to the Han dynasty can be called government official books era.Government official books have three features.First

prohibit public publishing.Second

the author does not sign.Third

books have no definite versions.Just because these three features

the government official books are very different from the books after the Han dynasty in the book existence and evolution.Prohibit public publishing means the government official books can not be published before the public which affects books mostly.No sign of the author means the idea of Copyright does not exist in that period and the real or fake for the works does not matter.Therefore

the idea of pseudo-book could not be established in the government official books era.No public publishing and no author’s sign make almost all the books are anonymous works and then the personal works are hard to survive.
