Song Henghang had a dream.
In the dream, she was a lady from an official family. She learned music, chess, calligraphy and painting from her grandmother since she was a child, embroidered women's clothing, and presided over the middle school. When she was a little older, she was sent to the palace by her family. She spent most of her life crawling around in the harem and was promoted to the position of noble concubine.
Then, Song Henghang woke up.
This dream was very real, as if she had really spent her whole life in that palace.
It turns out that she really spent her whole life in the palace.
