I had heard this was an amazing museum and I had wanted to come here for many years. It's reputation did not prepare me for the experience: it is overwhelming. The sheer size and scope are like nothing I have ever seen. Simply walking in is like approaching the palace of an emperor. It really depends upon you, but if you really want to experience it, I would say. that you should come on consecutive days. It takes a while to get the feeling of the general layout and I think there is so much to read and take in that you need time. The art is gorgeous, but the amount of information is also impressive. If you took the time to read even 10 % of the explanation on the signs it would take you many hours. You could learn so much about Chinese history! A simple bit of advice would be to come early, rather than in the afternoon when you might be tired. There are several smaller gift shops and a large, main one. The experience of a lifetime!
