Father Dong and Mother Dong were not initially from Mocheng.
The Dong Family did not have only one son either.
Originally, their family lived in another place. It was only when Dong Shanshan was three or four years old that they came to Mocheng to reunite with their grandparents.
Therefore, people in Mocheng who were on good terms with Father Dong did not know that Dong Shanshan's birth mother had passed away.
They also did not know that the current Mother Dong was a stepmother.
The Dong Family outwardly declared that Dong Shanshan's younger brother was one year her junior.
This way, no one would have any suspicions.
Furthermore, Mother Dong had a reputation for being a kind mother.
No one would ever imagine that she was a stepmother.
As far as Dong Shanshan herself was concerned, there was nothing about what Mother Dong did that could be faulted.
She was caring and considerate towards Dong Shanshan and never abused her.
