See, their triplets had been raised well by Qiao Nan. Even though Qiao Nan was always busy with her studies, the three children were still close to their mom. If Qiao Nan had not put enough effort into raising them, they would never have been so attached to her.
Children were the purest. They didn't use their eyes to judge a person, but their hearts.
As a mom who couldn't raise her children well, Miao Jing had no right to demand Zhai Hua or Zhai Sheng to be good parents. Miao Jing had not even felt it when Zhai Hua and Jiajia had been in a bad place, so there was no way she could expect Zhai Sheng to be that alert either.
It went without question that Zhai Sheng had only noticed because Qiao Nan had reminded him. That was enough. Her daughter-in-law cared for Hua Hua and Jiajia. Where else would she find such a good daughter-in-law?
