Why are the historical books written by ancient historians in China not detailed? How many people died in every detail of the fighting in European countries?

China and Europe have different cultural traditions. China people write history for the purpose of serving the ruling class and governing the country. Therefore, people are the most important thing. The official history is people-oriented, and it is also recorded, emphasizing strategy, such as the Warring States policy. The details of this movement are negligible in China's historical thoughts. Of course, China also has national epics similar to those in the West, but with mythical nature: Biography of King Gesar, Jianger and so on.
