Will the refined canvas fall off if it is too cold?

Experts suggest that the preservation conditions of oil paintings are humidity 55%~65%, temperature 20℃ and good ventilation. If you encounter "returning to the south", you'd better use a dehumidifier. If not, using the drying function of air conditioner will also help. If you need to leave home temporarily, you can close the doors and windows, or put the oil painting in a box for safekeeping.
