The south wind means unity, harmony, helping others, generosity, atmosphere, wit, momentum, grace and so on. Nanfeng is a Chinese word. As a word, it refers to the wind blowing from the south to the north, and it is extended to the wind in the south. In ancient poetry, the south wind is often used to express a person's feelings, for example, only the south wind knows an old friend, stealing doors and turning over books. Expressed the mood of joy.

South wind reason:

The high indoor moisture regain in spring is because the temperature of indoor walls and floors drops day by day after winter. After spring, the indoor heating rate is slower than that outside. When the outdoor air suddenly rises sharply and is very humid, it will condense into small water droplets on the cold ground and walls, and even form a flowing water layer. If it is cloudy in the morning, the weather is too warm and there is a strong south wind, there will be a resurgence that day.

As the saying goes, the south wind warms the north wind, and the east wind is wet and the west wind is dry. People often say that "the sky facing south" is not a specific term in meteorology. But literally, it can be understood that this resurgence phenomenon is related to the warmer south wind, which often occurs every spring or rainy season. After beginning of spring every year, some areas will have the phenomenon of indoor moisture and water, which makes clothes and furniture damp and moldy, which is often called southerly weather.
