I enjoyed this model, it is very attractive and makes me want to travel to China to see the real thing. The build is very interesting, there are no real confusing steps in it. It goes together very quickly. Even when in the initial sreps yo do not think it is going to work, it does. I loved the way the joints were combined to make a continuous run (apparently). Whoever designed it had a great idea, and implemented it well. Architecture may one day take over from my favorite sets (Technic) if the designers can keep the high quality sets going like this one.
