Su Jinghong, a prairie princess, married into the palace with her falconry skills, and discovered that Emperor Li Mu was a medicine jar that was ignored by powerful officials. During the day, she accompanied the Queen Mother to listen to the opera, and at night, she used falcon messengers to send messages to the old department.

I borrowed the 300,000 troops and horses in the north three years ago."
