One year later...
"Oh, baby, you're Grandma! Call me Grandma!" Mrs. Zhang said with a smile, holding the baby. Zhang Hua entered the room and saw his mother holding and playing with a baby. "Whose child is this?" Zhang Hua asked. "Of course it's your son! Who else could it be?" Mrs. Zhang said. "Mine? Did you do a paternity test? Don't just claim anyone else's," Zhang Hua said.
"I only brought the baby in after I had a paternity test done to confirm that he was your child," Mrs. Zhang said.
"How did you get the child?" Zhang Hua asked. "Oh, a woman said this was your child, and then she came with me to the hospital to have a paternity test done to confirm it was the baby, and then we brought her home," Mrs. Zhang explained. "Did you see what that woman looked like?" Zhang Hua asked. "No, she was wearing a mask the whole time," Mrs. Zhang said. "To get the child registered, you should marry your current girlfriend," Mrs. Zhang said. "But my girlfriend is pregnant," Zhang Hua said. "That would be even better," Mrs. Zhang said happily. "Mom, what is this?"
"What do you mean?" Zhang Hua asked, confused. "Mom means you can get married, but you need to register this baby's birth," Madam Zhang instructed. "I know you don't want this child, so Mom will help you register your marriage," Madam Zhang said. "Thank you, Mom," Zhang Hua said. Watching Zhang Hua walk away, Madam Zhang breathed a sigh of relief.
