Because the hot air rises, fishing for a long time found that the temperature at the top of the tent was very high, and it became lower and lower when there was no air disturbance, so a small fan was added to let the hot air flow downward.
Ice fishing refers to the freezing of rivers and lakes. Generally, when the thickness of ice reaches 8 to 10 cm, ice fishing can be carried out. The most important thing in ice fishing is to pay attention to safety.
