Recently there have been a lot of changes in the weather. Even though it looks the same at first glance, hot and sunny, lurking inside there can be an amber-level rainstorm or an approaching typhoon, as there is now. There's a tropical cyclone coming towards Hong Kong. No wonder I felt muggy as well as hot yesterday. I had only worked outside for a short time before I had to start drinking water. You guys have to be sure and keep yourselves hydrated when working outdoors.
