As for the Yuan family, the old lady had interacted with them before.
She knew that the Yuan family's parents favored sons over daughters, but in this day and age, there were very few who did not favor sons over daughters. There was not even one in a hundred the old lady who was as understanding as her.
However, at least the Yuan family's parents did not go overboard. They were not like some families who could drown their daughters right after they were born. Those were the scariest.
The old lady also knew that the eldest son was the person that the Yuan family's parents valued the most. However, they did not treat the remaining three sons differently.
Therefore, to the old lady, the Yuan family was much stronger than the average family.
