Qingping has been serving Old Madam for quite some years now.
She manages quite a few matters in Old Madam's quarters and knows many of the Cui Mansion's hidden affairs.
Old Madam has been through the ups and downs of these decades since she came into this family as a granddaughter-in-law, and now she is a grandmother. It has not been easy, but her survival to this day surely relies on her wisdom.
Despite Old Madam's apparent disengagement from household affairs now, nothing big or small in the mansion escapes her notice.
Whatever issue arises in any part of the household, whoever does whatever, she always finds out about it at the earliest.
Cui Yiran considers himself careful in his actions, making many arrangements behind Old Madam's back, but Old Madam has long been aware of them.
If Old Madam knows, then surely Qingping does too.
