It was too late to buy tickets on the official website, so I couldn't buy any. I had to join the tour group. The registration was at 11 o'clock, but the agent changed it to 12 o'clock. The tour guide's commentary was very interesting! The church is huge and majestic! The bell tower is the tallest in the city. Walk up the 23-story slope and the view is super beautiful! There are a lot of people at the scene, if you want to take pictures, you need to allow more time to wait
