I'm secretly planning a trip for my parents who are in their 70s. They've never been further than Greece and really want to see the Great Wall of China. My only concern is - Beijing air quality in the spring months and the possibility of a dust storm because one of my parents has mild COPD.
I've seen that dust storms are becoming more frequent and can leave people housebound for days at a time. In addition to this, Beijing doesn't have good air at the best of times https://www.iqair.com/china/beijing
Not set on going in Spring (was really just for the added bonus of the gardens).
For those that live / travel / familiar with Beijing do you have any recommendations for months of travel? Should I avoid the spring months?
Many thanks !!!
