Shao Xuan is the daughter of Shao Qing. Shao Qing is quite influential in Zheng State. Of course, it would be better if he has not thought about seeking power and usurping the throne.
After Shao Qing failed, he was like a lost dog, being chased by the enemy. Shao Xuan followed Shao Qing to escape for his life. Shao Qing saw that he could not escape, but his daughter had to live anyway, so when he passed a village, he pushed his daughter Shao Xuan down and ran away.
