Hello, Very pleased with the service provided. Good english and mandarin explanation of all sites visited. The restaurant we were taken to for lunch was very over-priced, but I suppose this is normal around the area of the terracotta warriors. No big problem. We were surprised at the end to be asked for a 200+ rmb tip. We were planning to tip but on the request of such a large tip we were slightly offended and no longer wanted to tip. This may just be a difference in customs, so again, no real problem. Over all, very happy! Thank you!
