The specific thing is this. According to the TV series, when Bao Zheng was born, his skin was very dark. And there is a crescent birthmark on his forehead. His parents thought that he would bring misfortune to his family, so they abandoned Bao Zheng. At this time, Bao Zheng's sister-in-law saw that Bao Zheng was abandoned, and felt that it was too cruel to a newborn baby who knew nothing. Later, she took Bao Zheng home to raise, and Bao Zheng called her mother at first.
So what does history say? In fact, there is no mention in history that Bao Zheng was supported by his sister-in-law when he was young. And according to historical records, Bao Zheng is a very filial parent. He even gave up his good career prospects because his parents were too old to let him leave their side. Go back to your parents and serve them wholeheartedly. It was not until later that his parents left the personnel department to support the elderly. After their death, Bao Zheng personally built a thatched cottage beside their cemetery, left after the funeral and continued his official career.
Therefore, judging from Bao Zheng's attitude towards his parents in history, he doesn't look like a person who was abandoned by his parents and raised by his sister-in-law. So personally, I don't think what Bao Zheng said should be mentioned by his sister-in-law.
