Baoding Sight Seeing

I'm visiting Baoding for a couple of days to give a talk at Hebei University. Baoding is about 80 miles south of Beijing. I was escorted on the train trip from Beijing by Yafeng He, a student in the group I am visiting. On Saturday he and Weili Fan and Weili Liu, two other students in the group, took me on a sight seeing tour of the nearby Han Tombs, and the Governor's Office and Lotus Gardens in the city. The Han Tombs are the burial chambers of a Chinese emperor from about 2000 years ago, in caves excavated in the limestone hillside, that were not discovered unitl 1968. These were perhaps the most impressive part of the tour, but no photos were allowed inside.
