On the contrary, the daughter-in-law held a trump card that could control her, and she treasured it as if it were her own. Just like the IOU Manman held, which could be used in court to seize Jiang Fei's property. Similarly, the fact that her eldest daughter-in-law was clinging to life in the hospital ensured that her son Jiang Fei had not yet committed a murder and been sentenced to death, and this was not unrelated to Manman supporting Jin Meichen's substantial hospital expenses.
Little did she know the thought in Manman's mind: keeping Jin Meichen alive was merely to let Meichen die of anger someday. At least, Meichen had to stay alive until her own child was born.
For Jiang's mother, what mattered most was that the child inside Manman, who was said to be a grandson, was what made her bow her head in front of Manman.
