We are planning to visit kunming in first week of December with kids. How will be the weather ?

According to the previous statistics, the temperature of that period of time is 39.2 °F to 62.6 °F.
It's cool and comfortable. Light jackets, T-shirts and jeans are enought for you to prepare.

As far as I know, there are lots of sports shops in Nanping Street, Wuhua District that sell many kinds of sporting clothes and goods. Hope you like.
