Like others I visited the Changling Tomb. I visited China the first time in 2006, and at the time I was not even aware of Unesco. I enjoyed my time at the tombs, while I was not rushed, I did feel there was so much more to explore.
It turned out I was right, when later I re-visited my pictures concerning the Ming Tombs, I realized I visited only one part of a huge complex of tombs. In the future I would like to make plans to visit some of the Ming Tombs around Nanjing. Particularly, after visiting so much of the Joseon tombs, it would be fascinating to explore more of the Ming sites in depth.
When I visited the Changling Tomb it was one of my first days in China, and I was pretty much "going along for the ride". I had little to do with the planning and everything was so new and interesting to me, my senses were on overdrive. It was also one of my first intertnational experiences. Now after much more experience in Asia, I would love to visit China a 3rd time and explore the country based on my own itinerary.
