Do you know hui nan tian, or ongoing wetweather?
Hui nan tian is a special kind of weather inSoutheast China in spring, when it becomeswarmer and warmer. Before it comes, there usuallyhas been a few cold days, with a temperaturebelow (在……以下) 12℃. After the cold air goesaway, warmer air quickly comes and gets cooler, creating a lot of water in the air. So you can see small water drops on windows and walls.
Ongoing wet weather makes it easy for bacteria (细菌) to grow. Food goes bad easily, clothes stay wet, and sofas can get wet. The things like TV sets and fridges may break down when they get wet inside. It's dangerous because you may get an electric shock (电击) when turning them on.
Wet weather also makes people feel tired and even sick. People can catch a cold easily during this time, as the temperature changes fast.
Although the weather troubles people a lot, for nature, it can be helpful. Thanks to hui nan tian, plants can grow better with enough water and warmer air.
