This will happen. I think it's better to find a male nanny to take care of the elderly in bed. After all, men are much stronger than women, and it takes strength for old people to turn over and go to the toilet. If you want to find a male nanny, you can look at Beijing Ruizhi Hongda Home Economics. They also have their own nanny training institutions, and it should be ok to run housekeeping in Beijing for so many years.
