Andreas went to Yinchuan yesterday to examine several Great Walls there. It was pretty cold today he said. And it is cold here too. I left Yulin for Datong today. Datong is where I have stored a very warm sleeping bag, extra sleeping mattress and warm down coat. I spent a couple of hours on a bus, and then about six hours on the train. Have just booked tickets to get to Hong Kong to get a new visa. The plane leaves tomorrow morning.
It is going to be minus 19 degrees C tonight (-2 F) which is about the limit of what the warm sleeping bag, the tent and I can handle. Tomorrow evening, I will experience about plus 20 degrees C (+68 F) Sounds perfect!
As Sue mentioned in comments, there has been extreme weather in Northern China recently, and unfortunately quite a few deaths as a result. About half of them due to traffic accidents. The province Andreas and I walked in – Shaanxi – was also hit, so it was probably wise to stop walking when we did. The snow fall is the heaviest since keeping records began in 1949.
