Right behind the St. Paul's archway. Although my mystery of Macau has been reduced a lot more than before, but after all, I have been out of customs for the first time, so I am still very curious about the surrounding situation. It is obvious that the streets are particularly narrow. Some residential areas and commercial areas are very dense. The old buildings are similar to the arcades in the Xiguan area of old Guangzhou. Just came from Zhuhai, the street is spacious and straight, the contrast is too strong, and it is really a little uncomfortable for a while.
