Returning from the Hospital, He Slaps the Cousin Who Occupied the Magpie's Nest.

The Queen Mother suddenly fell seriously ill during the ceremony, and the Emperor issued a decree to select a noblewoman from aristocratic families to go to Mount Wutai to attend to her illness. When my cousin was selected, my mother cried uncontrollably and begged me to go to the hospital for my cousin: "Your cousin's parents died when she was young, and she is weak. If she goes to the hospital, she may never come back." "You have been practicing martial arts with your father since you were a child, and you are strong. How about you go for your sister?" I couldn't bear my mother crying day and night, so I agreed to take my cousin's place and go to Mount Wutai to attend to her illness, and I stayed there for three years. Finally, when the Queen Mother recovered and returned to Beijing, I hurried home and found that Mrs. Jing'an was holding a ceremony for her eldest daughter. However, I am still in Wutai Mountain, and my mother is going to marry her daughter? Who is she marrying?
