If the house in Beidaihe doesn't live in winter, will the water pipes freeze and crack?

Yes, it will freeze, especially in some communities, and the occupancy rate is not high. At present, there are many people who can provide water blowing business. In fact, it is very simple, that is, use an air pump to blow the water out of the water heater, usually into the sewer. Our house has just been blown down. It's better to blow it up, or it will be difficult to repair it if it cracks.
