Madam Cui's heart condition is now under control, but in Jiang Xiao's view, she probably has an emotional ailment. Emotional ailments are hard to cure, and if not completely treated, there's a possibility of relapse in the future.
That's why Jiang Xiao actually wants to know what the situation with the Cui Family is really like.
She feels uneasy because if the Cui Family is reliable, Madam Cui wouldn't have had to stay in the sanatorium for years.
Though having a full house of children and grandchildren with both sons and daughters, she still has to live alone in the sanatorium, which seems somewhat off.
What if she relapses shortly after returning home?
There's also Commander Cui.
To Jiang Xiao, Commander Cui also seems to have some old ailments, but he might have maintained good eating and living habits over the years, so those ailments have remained under control.
But who knows what would happen if he gets too busy for a time, disrupting his good eating and living habits.
