Dear Friend Thank you taking your valuable time to write a review for us. About your issue. On the website, it's very clear. With pre-booked admission, use your passport to access at the main entrance, directly across from Tiananmen Gate. Take this chance, we also want to clearfied some important informations about the ticket service. The first, to buy the ticket on our webisite, must provide all the passport numbers,leave all the passport number in the same form is fine. Because the passport gona to be your ticket. If any number not correct(it's happened many times already), you won't be able to go inside. The second, this ticket is only valid for the travel day, any other days will not working. The third, with the same passport number, only could buy one ticket a day. That means, if your passort information is in the system during the day, you cann't buy ticket anymore. Regards Lily
