How to mop the floor when returning to Nantian

Go back to Nantian and mop the floor with salt water.

First, we heat water until it becomes a temperature that will not be hot. At this time, the water temperature is about 40 degrees Celsius. Then, we add a spoonful of salt to the water and stir it a little. When the salt is completely dissolved, we can start mopping the floor. Soak the mop in hot salt water, wring it out as much as possible, and mop the floor clean.

The principle of doing this is because the evaporation speed of liquid is related to temperature. The higher the temperature, the faster the volatilization speed, and the floor with warm water will naturally dry quickly. Moreover, magnesium chloride and calcium chloride in salt have strong water absorption. After drying on the floor, they become small particles, which can keep the floor dry for a long time, and finally drag it with a dry mop.

Hui Nantian introduced

Hui Nan Tian is the name of a weather phenomenon in the south of China, which usually refers to the phenomenon that the temperature starts to get warmer and the humidity rises sharply every spring. When Return to the South Sky appeared, the air humidity was close to saturation, and there were wet scenes everywhere.

South China belongs to a typical subtropical monsoon climate. Therefore, from March to April every year, warm and humid air from the South China Sea meets cold air from Siberia, forming a quasi-static front in the south, which makes the weather in the south changeable and very humid, with light rain or fog during the period, resulting in the phenomenon of returning to the south. Some cold objects begin to condense after encountering warm and humid airflow, forming water droplets on the surface of the objects.
