She lived with Sun Xiaoming, gave birth to a son and a daughter, educated her children, and lived with hope. Xiaorui was also a victim of the marriage exchange. She was high-spirited and longed for the big city. She couldn't bear the poverty of rural life and chose to escape. Eventually she lost her fertility. Finally, she realized the true meaning of happiness in life and returned to her family.
