On the way back from the Visa visit in Hong Kong, I spent an evening with Kelly in Beijing. He and my brother studied Chinese together in Beijing, and the last half year we have gotten to know each other. He gave me an inspirational speech, and without going into any details, thanks a lot for the advice!
The last two weeks I have walked a respectable distance in pretty cold conditions. The trick now is to get all the practical stuff in Datong done as quickly as possible before returning to the Great Wall.
