The first volume of History of Northeast China was written by Fu Si-nian in a rush after the 9.18 Manchurian Incident, in the hope of convincing Lytton Commission of the League of Nations that the Northeast has always been Chinese territory from time immemorial. Based on historical facts, this book aims to prove that Northeast belongs to China and refutes the Japanese fallacy that historically its not Chinese territory. The book was later translated into English by Li Ji-jie.
