Shao, our guide, was the most professional I've ever met. He was fluent in three languages and his explanations were incredibly comprehensive. When we stopped at scenic spots, he diligently took photos and provided explanations. He even helped us order food at the same restaurants if we happened to be there. He managed the time perfectly; thankfully, despite the large group, everyone was punctual. On the return trip, he thoughtfully recommended popular drugstores and restaurants, providing exactly the information we needed.
