The overall experience of this one-day tour (including the observation deck) was fantastic. Both the itinerary and the service quality were very satisfying. I especially want to commend our tour guide, Liu Mei. Her explanations were incredibly detailed, giving us a deeper understanding of the attractions, and we could ask her any questions at any time, which she would patiently answer. What's even more thoughtful is that she would proactively check if special attractions were open for us, and if they were, she would immediately send a message to notify everyone, allowing us to seize the opportunity to visit and take photos. Overall, it was a very pleasant and highly recommended trip!
