Do you think it is appropriate to open the window for ventilation in rainy days?

It is advisable to open the window for ventilation in rainy weather (except when the outdoor temperature is lower than 15 in winter). Because the air outside the window is cool and fresh, people enter the room from the outside and obviously feel that the air is not fresh. It is urgent to open the window, let the cool and fresh air outside the window enter the room, and eliminate the discomfort caused by the temperature drop. After opening the window 15 minutes, it can be switched according to the actual situation. If you want to lock the door for a long time or have questions, close the window before you leave.
