After moving, all the family members have health problems.

It seems that what you want to hear is a metaphysical answer My answer is only based on the actual situation.

When you move to a new house, it is normal to have health problems. Because you have suddenly changed to a new living environment, it is inevitable that you will feel uncomfortable. Especially the new house now. Decorating with many chemical synthetic decoration materials, those chemicals will dilute some toxic gases for a period of time, which is not good for human body. So it will be bad for your health. One month or half a month before check-in, it is best to put some indoor plants in the lobby and room of the house to absorb gas. Open the window for ventilation in a limited time every day to replenish fresh air and reduce the accumulation of toxic gases. This will reduce the harm to the body after checking in.
