The Maid of Twenty Years Is My Mother, and I Am the Real Daughter.

My name is Zhang Yunshu, and I have been the adopted daughter of the Zhang family for twenty years. I wrote a prescription and saved the Zhang family's company from bankruptcy. My credit was taken away by my sister, and I was locked up in a small dark room to die. That night, the most humble old servant in the family broke the door lock. She was soaked all over, pushed me into the van, and said: "Miss, this old slave has been preparing for twenty years."
