There is a large fort in Macau, built in 1616. It is one of the oldest western-style fortification groups in China. It was built to protect the church's priests from pirates. It was built by the church and later by the Portuguese. The government used military defensive positions and successfully resisted the Dutch invasion in 1662. Macau has never had a war on the mainland, so the fort has become the core of the Macau defense system. In Macau, although it is a tourist city, it is totally unpopular and buzzing in the mainland tourist cities, and there is no avant-garde in the coastal emerging cities. She is quiet most of the time, just like a lady quietly. Sitting on the shore of the sea, not showing off, not swaying, a sea breeze blowing Buddha, soaring her fragrant fragrance to the Quartet.
