Returning to Nantian is a phenomenon of warmer weather, which generally appears in February and March in spring. After the cold air left, the warm and humid air quickly counterattacked, resulting in an increase in temperature and air humidity. Some cold objects are easy to produce water droplets when they encounter warm and humid airflow. Cause furniture, floor, glass, etc. The phenomenon of water coming out. Generally speaking, the formation of returning to Nantian requires two conditions:
What does it mean to go back to Nantian? What are its influences and countermeasures?

The omen of returning to the south sky
Usually, after a cold air with obvious cooling is weakened, it is likely to return to the south when it encounters a warm and humid airflow from the sea and the air humidity is high. Therefore, when the relative humidity of the weather forecast reaches more than 90% and the wind direction is southerly or southerly, which happens to be two or three days after the cooling process is over, there is a great chance to return to the south. At the same time, the appearance of returning to the south sky is often related to the increase of relative humidity in the air. If the weather station forecasts fog, you should also pay attention. Although fog does not necessarily mean going back to the south for s days, it is often foggy when going back to the south.

How to deal with going back to Nantian?
Dehumidifier dehumidifies more easily than air conditioner.
Dehumidifier is more suitable for indoor dehumidification than air conditioner. Because the air conditioner dehumidifies, the indoor temperature will drop at the same time, and the room can be kept dry without opening the window, but the root cause of water vapor condensation has not been eliminated? The temperature difference between indoor and outdoor even increased it. Once the window is opened, the moisture regain will be more serious. Moreover, the indoor temperature is low and the body feels uncomfortable. Dehumidification with dehumidifier not only has a large amount of dehumidification, but also does not reduce the indoor temperature, and the effect is better than that of air conditioning.
Pay attention to open the window for ventilation when the north wind turns.
Pay attention to open the window for ventilation when the north wind turns. Due to the cold air heading south, more than 80% of the return days disappeared. If the weather forecast says that there is cold air going south and the local wind direction turns north, you can open the doors and windows for ventilation. After the arrival of cold air today, it may bring some rain. It is better to open the window to get some air and drive away the annoying return to Nantian.
4, hot water mopping the floor can evaporate water.
Spring is the season when the sun is the spirit of nature. The days get longer and the outdoor is warm. Lingnan area is humid in spring, and the humidity increases, so bacteria and viruses are easy to multiply. From the perspective of traditional Chinese medicine, the prevailing wind in spring is also a season of high incidence of infectious diseases, such as influenza, upper respiratory diseases and pneumonia in children. Because it has been cold indoors for a winter, the wet cold has not dissipated. Now that it's time to go back to Nantian, many Cantonese people like to close the windows. Chen Ruifang believes that although the weather is humid, it should be ventilated regularly to prevent viruses from gathering and keep the indoor air fresh. If you want to purify the indoor air and get rid of dampness, you can try steaming Atractylodes lancea. Because ultraviolet rays are used for steaming, if you smoke with alcohol, people need to leave the room, which is not good for electrical appliances and will rust. If Atractylodes lancea is used for steaming, people can continue to work and live indoors. It is suggested to buy a little Rhizoma Atractylodis, soak it in alcohol for three hours, and then steam it in a vessel, which has a good aromatic and dampness-removing effect. Another way to get rid of indoor cold is to mop the floor with hot water and evaporate water.
