The weather in Honghe Prefecture, Yunnan Province

Hello, I am self-taught, and now I am studying outside. According to my life experience of nearly 20 years, it is necessary to bring a thin sweater. Old people and children should wear more clothes and bring a coat. Don't need down jacket. It's still a little hot at noon. It doesn't snow there in winter, without exception, the lowest is 6-7 degrees.
