They don't call this city forbidden for nothing. The first time I went, they wouldn't let me in. This may have been do to me being an American or maybe because it closes at 4 and I got there at 4:30. Regardless, not to be deterred I went back a few days later to see the famous former palace. For those unaware, this place is massive. I think I walked around for near 3 hours and there was still things I did not see.
