The same masked warrior, why the blindfold in the west and the blindfold in China?

Because of different backgrounds. Chinese masks come from real life. In order to hide people's eyes and ears, thieves all over the world choose full coverage or masked masks, which are the same at all times and in all countries. The reason why the image of western superheroes is blindfolded is influenced by Zorro, whose mask comes from the ceremonial mask of the upper-class masquerade ball.
