Absolutely incredible seeing this in person! We went in the most crowded time during mid autumn holiday and were prepared for chaos. The tickets on the official website was sold out but through trip.com we managed to secure us tickets! And super convenient just bring your passport. Easy to navigate you honestly don’t need a guide unless your interested in learning about history. It was extremely crowded but luckily we come one hour before opening but after 30 minutes we were already through the passport check.
