Bai Jin Shang quickly thought of a countermeasure and immediately sent people to gather everyone in his wife and daughter's room and courtyard. He then announced a new rule.
In the future, the people on duty in the madam's and miss' room and courtyard would have to work in groups of three to monitor each other. Every day, they had to record the day's schedule, prepare food, and bring medicinal soup. The dregs and food residue were left for inspection. After the shift ended, the three of them would sign at the same time.
Apart from a few servants and old women who looked at each other and didn't know what had happened, the servant girls and old women who were close to him were all smart people. They immediately understood that there was a mole in the family and the master was investigating.
Everyone lowered their heads and did not dare to look at the people around them, for fear of getting suspected again.
