There are twelve volumes of the military book, the scrolls have the name of the grandfather, the grandfather has no eldest son, and Mulan has no eldest brother. It is precisely because of this situation that Hua Mulan, as a generation of heroines, served in the army for her father for twelve years, but it was not until they returned from victory that Mulan returned home and changed her outfit, and his comrades-in-arms knew that Mulan was a woman. The mirror appliqué is yellow, and the posture of the daughter is displayed. So in the twelve years they have been in the army together, why has no one found out that Mulan is a woman? Is Mulan really so good to hide? In fact, the reason for this is not that Mulan is well hidden.
First, Mulan may be a cavalryman, and the cavalry has an independent residence. Mulan had such a description before the expedition, the East Market bought saddle whips, the West Market bought the dragon head, the South Market bought horses, and the North Market bought long whips. This also shows that Mulan is likely to be a cavalryman, under the rules and regulations at that time, most of the cavalry stayed with their horses, that is to say, most of the cavalry will not sleep together, they have their own independent residence, with their own independent residence, then it is much more convenient, most people will not deliberately go to another person's place. It's normal not to find out.
Second, the harsh war environment is very damaging to Mulan's body, which is likely to cause amenorrhea. The ancient environment was originally very difficult, and there were no developed conditions like modern science and technology, especially the ancient war environment was very difficult, as we can see from the film and television works, the environment in the military is not the whole reality, in ancient times it will only be more difficult than this. For a woman, the harsh environment will definitely cause great damage to the body, causing endocrine system disorders, which in turn lead to amenorrhea is a very normal thing. And in ancient times women's menstruation was called Aoi Water. It is also possible that when Mulan joined the army, there was no sunflower water. Without such obvious features, it is normal for others not to find out.
Third, Mulan's official position in the military should not be low, and the twelve turns of the strategy are rewarded with hundreds of thousands of strong. Khan asked what he wanted, and Mulan didn't need Shang Shulang. Being able to get the Khan's personal inquiry shows that Mulan's official position in the army is not low, the ancient hierarchy is very clear, and it is possible that in the time of war, the residence of ordinary soldiers is very poor, but it does not mean that the residence of people with official positions in the army is also very poor. But anyone who has an official position will definitely have his own independent residence, Mulan can be personally rewarded by the Khan, the official position in the army must not be low, and it is very normal to have an independent residence. Having your own independent home, it is very simple to hide your female identity.
Therefore, it is precisely because of these three reasons that Mulan will be much more convenient in hiding her identity. And in these twelve years, the people around you can't change every time, and in these twelve years, there will definitely be many people who will continue to die in battle. Then these people can't fully understand Mulan. It is also normal not to know her female identity.
