Small bee groups are more sensitive to temperature, they will try every means to keep the temperature constant in North Korea, people have no way to real-time perception of the bellows temperature change, do not know when to open the fan to cool down, so the installation of fans is not feasible, the best way is to avoid direct sunlight, increase the right amount of vents can be.
Open hole of beehive and electric fan ventilation is not allowed.
