China Jilin got how many airport? How do I go there from Singapore?
Using the cheapest airline and at the fastest travel time?
Thank you.

As I know, there are three airports in the province. 
You can fly from Singapore to Beijing first and transfer to another plane from Beijing Capital Airport to Changchun Longjia Airport. 

What is the weather like in Jilin?

This location gives the province favorable temperate climate, which includes a lengthy winter with snow that can start as early as October and last until April. Despite the winter cold, people flock to this area for the Ice Lantern Festival and the winter sports. Jilin is known as an area for winter sports and has produced some of the best ski resorts in China. However, it has many other natural and historical attractions to entertain its residents and visitors.
