Winners Writing the History

There is a famous saying in the Chinese—‘The losers are always wrong’. A large number of things are determined by forces in this world throughout the whole history, as the resources are in scarcity and people are avid for more things to meet their needs.
As the wars begin, it must come out a result that who is the winner and who is the loser. There are many emperors in the Chinese history. For instance, Bang Liu defeated Yu Xiang and became the first emperor of the Han dynasty. As a result, later generation considered Yu Xiang to be silly and swollen with pride and that was why he became a loser. The truth may be not like that, however, Yu Xiang was a virtuous braver but Bang Liu was shady. The only reason the later generation believed like that is that the history was written by Bang Liu, the winner.
Suppose if the history was written by the loser, like Yu Xiang, it may not reflect the real history as well. The loser must avoid their faults and put the reason of their failures on the luck but not their own lacking.
In my opinion, the fairest way of writing the history is that the history was written by the third party that was not involved in the wars.
