 Luo Guanzhong also simplified some of the historical events, invented fictional battles, and changed the sequence of events.However, due to the popularity of the novel, many people hold the events detailed in the novel to be true, not knowing the true history as presented in definitive sources such as the "Book of the Later Han", "Records of the Three Kingdoms", or "Zizhi Tongjian".This fictional account of history is also adopted by many Chinese operas and video games.
