Gatekeeper, but I'm a Sixteen Year Old Girl

My name is Shen Zhaoniang, I am sixteen this year, and I am the gatekeeper of Jiayuguan. Don't laugh. I know what you're thinking - shouldn't the gatekeeper be a tough guy with a sinister face? But my father's leg was broken, my brother died in the battle, and I was the only one on the military register who could breathe. Others rely on knives to protect themselves, but I rely on... Embroidery. Embroidered military flags for the guerrilla general's mansion, embroidered purses for passing Hu merchants, and embroidered kneepads for veterans on the pier. Embroidering and embroidering, the secrets of Guancheng are embroidered. That down-and-out scholar Mr. Chen said that I should be literate, that Hu merchant from the Western Region Sai Maiti said that I should settle accounts, and that Qiang boy Asang said - there are people outside the customs who want to see me. OK. Just guard the gate, solve a case, fall in love, and then guard the last gate of the Great Wall. At the foot of Jiayu Pass, beside the Nine Eyes Spring, is the story of a girl and a majestic pass.
