Tan Da (1889-1939), whose real name is Nguyen Khac Hieu, is a famous poet, writer and playwright of Vietnam. In Vietnamese literature at the beginning of the 20th century, Tan Da emerged as a bright star, both unique and abundant in writing in many fields. In the catalogs that have left Tan Da's own mark, the book "Quoc Su Huan Mong" (Teaching children Vietnamese history) is regarded as the earliest historical textbook compiled (1924). This is a great history book, but from the day it was born until now has not been reprinted. That book is only in the rare book category. This edition was restored intact based on the publication of Nghiem Ham An Quan published in 1924.
