Overall, I was satisfied with the experience, and all itineraries were completed on time. I especially commend tour guides Cheng Mengmeng (East Line), Jing Jing (Hukou), and Xiao Liu (Huashan) for their meticulous professionalism, which saved a lot of time. Here are a few points of feedback for the travel agency to improve upon: The four-diamond hotel (Hanguang) was booked as a non-smoking room, but we were given a room with a strong smoke odor. Although we immediately requested a change to a slightly smaller room, the internet didn't work, and the shower leaked. For transportation, two days had VIP first-class coaches, which were very comfortable, but some other coaches were very ordinary. I hope the tour guides can remind passengers to use headphones and not play videos on speaker, so that those who need to rest can do so peacefully. Regarding the itinerary: Maoling was said to be optional, but the local guide still required us to purchase tickets and enter. At the Yellow Emperor's Mausoleum, there was a worship ceremony, and yellow scarves were given to everyone without prior notice of a charge, only to be told at the end that each scarf cost RM10, which left a bad impression. Other chargeable items and performances were clearly communicated in advance, allowing guests to freely choose to purchase them.
