Located in the easternmost part of the Caribbean Antilles, Puerto Rico is the smallest island in the Greater Antilles. Such a Puerto Rican, a Spanish colony 100 years ago, is now a free state of the United States. There is a modern resort hotel in the capital of San Juan, the capital of the capital, which shows people like the American resort. However, the Old San Juan, which is only a few kilometers away, still maintains the 16th century , which feels like pirates will appear at any time. Walking in the old town of San Juan, it is like stepping into a time tunnel. The colorful architecture declares how the life of the locals is colorful; the fortress fortress whispers how people defend their islands in the era of pirates; the fresh and cool sea breeze calls, here is the Caribbean Sea, The place full of strange legends. And I was at sunset, with a cat, watching a beautiful sunset. I believe that when you visit Puerto Rico, you will also feel the fierce conflict and subtle fusion of American, Spanish and Caribbean cultures.
