This was one of my first conversations and I was very pleased with it. The presenter was well-versed in Chinese history and lore. I especially liked the overall look at the emperor’s tomb complex and the schematics regarding where the terracotta warriors are buried. I thought it was all together in the same place. I asked a question about lisar scanning which can give a non-invasive look at what lays beneath the mound but the presenter apparently was not aware of this new technology. I wonder if the Chinese are using it to learn more about what lies underneath. Nevertheless I thoroughly enjoyed this presentation and will follow up with any Chinese themed conversation in the future. Thank you for providing these amenable learning experiences.
