Introduction to Putonghua
Guoyu, also known as Chunqiu Zhuan or Zuoshi Family Biography, is the earliest national history book in China, which was reportedly written by Zuo Qiuming in the Spring and Autumn Period.
Legend is a national style work written by Zuo Qiuming in the Spring and Autumn Period. Since the Song Dynasty, many scholars, including Kang Youwei, have suspected that Guoyu is a fake of Liu Xin in the Western Han Dynasty. This book covers the period from the 12th year of Zhou Muwang (990 BC) to the Crusade to the West (about 947 BC) to the demise of Zhi Bo (453 BC). "Mandarin" includes courtship, feasting, satire, argument, response and some historical events and legends among nobles of various countries. Guoyu is the first national history book in China.
