an amazing place, security outside was really lovely especially me being so confused looking like a proper tourist. one of the few major tourist attractions they accepted i can speak both chinese and english (completely mad i know) but is filled with an enormous amount of rich history about china great for an all day event as my chinese cousin had to rush home to fetch her chinese ID card in addition to having separate lines with nationals and foreigners only took a sec for me and my partner (the foreign nationals) to go through security the security guard shouted at me on accident and pushed me quite hard when telling me to turn around but quickly apologised which was nice haha but having to wait for my 90 yr old chinese grandad in the chinese nationals security line took ages for him to come through as they gave him a full security check which i thought was a bit strange.it is truly a lovely museum next only had 2 hours to spend and was only able to go through half of the underground portion cos of our little hiccup. will deffo be back next time fully prepared. would suggest if want to visit to clear a full day for this and make sure everyone has their passport or chinese ID card on them as they would not accept my cousins driving license or my grandad's alternate senior ID. highly recommend to anyone visiting beijing whether they are on a excursion or live in the country.
