The origin of the name Guo Jing.

Guo Jing's father and Yang Kang's father are sworn brothers.

They made a vow. If the other party gave birth to a daughter, and if they gave birth to a boy, they meant to get married.

If they were both men, they became sworn brothers.

Later, they all gave birth to boys. At that time, Jing Kang's shame had just passed. Please remember. < p
