I am extremely happy with the service that Tour guide Duy provided to me and ny friends. He is a friendly, knowledgeable as well as a humorous guy. He answer very well to all our questions and able to joke during his tour. He speak very good english and i am extremely surprised he do know a little mandarin as well. The whole experience is full of knowledge and laughters. I will definitely recommended him to anyone who want to go for this tour. 5* to Duy and his company!
