Cheng Ling had met Qi Min a few times before. She was the grandmother of a classmate in Yuya First High School. That classmate had a good relationship with Cheng Xiao and would occasionally come to visit Cheng Xiao.
Qi Min was about the same age as Xie Ying. She would come and chat with Xie Ying when her granddaughter was playing with Cheng Xiao.
Cheng Ling put her bag on the sofa and greeted Qi Min respectfully.
"Grandma Qi."
Seeing Cheng Ling, Qi Min put on a smile. It was a very polite smile.
"Oh, Cheng Ling is back."
Qi Min had been here a few times, so she had some understanding of the Cheng family's relationship.
In addition, Xie Wan was a person who couldn't keep her mouth shut. To her, there was no such thing as not washing the family's dirty linen in public. Thus Qi min naturally knew about Cheng Ling's relationship with the Cheng family.
