Twilight Smoke Paints the Pavilion

One moment she was time-traveling, the next, Zhang Xiaoying, a lifelong singleton, skipped right over marriage and childbirth to joyfully become an amazing old lady.
She started with nothing but four walls and was gifted three sons and a daughter, each more infuriating than the last.
What could she do? She rolled up her sleeves and started whipping them into shape.
Not listening? A fist is the best argument, and good behavior comes from the stick’s end.
As days got better, the family realized that more and more officials and noblemen were visiting the old lady, wanting to take her away for retirement!
No way, it’s only right for sons to support their mother in her old age. Even the Emperor has to get in line!
The Emperor: “The teacher is mine; whoever dares compete with me for the privilege of caring for her in her old age, I shall decimate their nine relatives!”
Zhang Xiaoying: “Scared, so scared. This pile of pampering can go to whoever wants it; all I want to do is retire quietly.”
