Peaceful Elite was a very popular multiplayer online game. Substitute training referred to the behavior of the substitute player to practice or increase their level in the game. Usually, the leveling was tied to the game account, so whether a girl could go to the Peace Elite to do leveling depended on whether they had an ID card and driver's license tied to the game account. In addition, Peace Elite was a competitive game. The purpose of leveling up was to help other players improve their game skills, not to help them win the game. Therefore, if a girl were to practice on the Peace Elite, it might violate the rules of the game and might have a negative impact on other players. In summary, whether girls could go to the Peace Elite to do the leveling depended on whether they had an ID card and driver's license bound to the game account and had to abide by the game rules and moral standards.
