Take the bus to the center of Macau and go back to the complex jerky street, you can see St. Paul's church in the distance. It is said that the three fires in 1835 left only the front and stairs of the building. There are many steep stairs in front of the cathedral, which were crowded with many tourists. If you go up the stairs for a long time, you will see the magnificent front of the cathedral, and if you look closely at the wall, you can see delicate and beautiful sculptures. It can be guessed why it was designated as a UNESCO World Heritage Site. If you go up to the back of the front of the cathedral, you can see many coins thrown by tourists and you can see the city of Macau at a glance. Going down to the basement in the back, there are small tombs with tomb relics presumed to be from Father Alexander Ballignano, the founder of St. Paul's University, and the remains of many cathedrals.
