As for cultivating people's doubts, to be honest, if it weren't for historians, junior high school students, writers or cartoonists, how many people would care about these past histories. I feel that many people just think too much. Whether an animation follows the history in the book does not have much influence on everyone's life. Who will doubt other history if nothing happens?
Finally, Wu's is not for children, junior high school students and senior high school students, nor for them to learn history. Why not go to see a documentary? As a college student, I have studied history. I already have a scale in my mind, and I don't need to learn anything from an animation, so it doesn't matter.
Similarly, everyone supports the mysterious Wu. The portrayal of characters, especially the protagonist, is very realistic and three-dimensional, and it is definitely a good animation.
