Xi, the weather in February

Xi 'an is not very cold and sunny these two days, but this week, the sun will hide in the clouds from time to time. It is recommended to bring a thin down jacket. After all, it's still a little cold sooner or later. It's even colder if you want to go to the scenic spots outside the city, but if you have a lot of exercise, such as climbing mountains, you don't need to wear thick clothes. I can always think of the weather and scenery in Xi 'an. Hope to adopt, thank you!
