As for the real reason of the secret, no one knows. When Emperor Xuanzong of the Tang Dynasty drove Yang Guifei back to her family for the first time, she couldn't eat or sleep. He took Yang Guifei back that day, which was a bit contradictory. But when he rushed back to her home for the second time, Emperor Xuanzong of Tang Dynasty controlled himself and said nothing to Yang Guifei. Nothing happened for several days. This is the Yang family's urgency and all the favor.
Moon Hee said to Xuanzong: The imperial concubine is the woman beside you. You can kill her if you want, but you must not let her be humiliated outside. It is undoubtedly telling Xuanzong that Yang Guifei is your wife and you should handle things behind closed doors. How can you open the door and let everyone see the joke, and then send someone to see Yang Guifei, who is crying beautifully, and cut off her hair to bid farewell? Xuanzong couldn't bear to take away Yang Guifei when he saw it, so he took it away.
Therefore, this has nothing to do with Wang Ning. It's completely a little emotional appeal before Yang Guifei and Tang Xuanzong. According to this storm, everyone realized their position in each other's minds, cherished each other more and loved each other more!
