… or are postcards sent from Germany to China via Chile?
Some German stamps have a QR code for tracking. A few days ago I’ve sent a postcard to China. I guess they are not being routed over Chile to reach China? My handwriting seems to be illegible. 
That means it will go to Chile and then on it‘s way to China or right in the bin?
BTW … I‘ve sent 8 postcards to China in total since 2019 and there wasn‘t any loss even I don‘t print the address in Chinese characters.
