Tickets for the Czech Boys'Choir, previously booked online, will perform at 7:30 p.m. on August 17. After visiting the Palace Museum, the three of us went back to the hotel for a rest and then set out. At 6:30, we arrived at the National Grand Theatre, which is located on the west side of Tiananmen Square. The location is very easy to find. It is a semi-circular building. The museum is very beautiful. There are many art shows on the same day. We started visiting the underground ticket office when we reported our mobile phone number for registration. It is strongly recommended that there be many exhibitions and places to visit in the theatre as early as 2 hours, which is very worth visiting and enjoying. We came late and didn't see many places. It's a pity.
