First Time to visit China with 3 kids

Hi, I would tell you that the Great Wall is far from Yunnan. If u don't care about the distance, it is surley possible to see that once you go to China.

Well, the sections in Beijing are the most popular with all visitors. And there is direct airplane service from LJ to Beijing and it takes 3 hours or a little longer. Upon getting to Beiing, you can consider taking a taxi to the Badaling or Mutianyu Great Wall in 1-1.5h.
