At Moyu Pass in the western border, bones are buried in the yellow sand, and there is no spring all year round.
Guard general Gu Huai has been stationed for three years, calming down the border war smoke with his courage and bravery. Ah Qiao, a medical girl from the Central Plains, boiled medicine with bare hands and saved lives in the wind and sand. Although the two did not interact much, they secretly developed feelings for each other. They took half a camel bell seal as a token and agreed to return to the south of the Yangtze River together to enjoy the apricot rain together when the smoke of the war cleared.
In the cold winter of that year, the enemy from the north came in force, the isolated city was besieged, and food and support were cut off. Gu Huai decided to personally lead the dead soldiers to attack the enemy camp at night, and did not dare to say goodbye to Ah Qiao before leaving. In front of the tent on a cold night, she arrived with a medicine bag, pressed the golden sore medicine she had made overnight and her half camel bell mark into his palm, and said softly: "I'll wait for you to come back."
After a great victory in the night attack, the enemy troops retreated. Gu Huai was hit by three arrows and fell into coma for seven days before he woke up. But when he woke up, Ah Qiao had already contracted the plague from taking care of the wounded soldiers for many days, and was buried on a sand slope outside the pass. There was only a silver hairpin that she often used to pick out medicine residues slanted in front of the grave.
Later, the war subsided, and Moyu Pass became peaceful year after year. Gu Huai guarded the gate with his old head, always holding the two halves of the camel bell seal in his palm. He had guarded thousands of miles of mountains and rivers, but in the end he never found the person who would accompany him to see the apricot blossoms. Every time the wind blows, the camel bell rings softly, as if an old friend is still standing outside the tent, gently calling him to drink medicine.
