聖地亞哥是美國的海軍駐紮地區，我們遊覽時乘船遠眺了航空母艦，還可以上船参觀二戰時期的老航空母艦。還有一座“勝利之吻”的雕塑。

位於美國加利福尼亞州聖地亞哥城，這也是一個軍港，島上很漂亮。

很有意思的地方，可以出海看鯨魚

Santiago Port, the largest port of the U.S. Navy's Pacific Fleet, is home to several naval aircraft carriers. When we arrived, the tour guide said that if we were lucky enough to see the carrier, we would not only see the carrier, but also the carrier fleet. In the movies and TV, we often saw that the carrier was only a fleet. What we saw here was the fleet group. Usually an aircraft carrier would form a fleet with several auxiliary ships such as supply, medical treatment, refueling and so on. We saw five aircraft carriers. What a stir. The tour guide said that we were lucky to catch up with the supply of foreign ships. So the battle was huge. The whole coast was full. We traveled half the Strait by boat, full of warships. It was shocking.

Very beautiful western city of America! It was already evening when we drove to the airport and ate the famous Korean barbecue. The next day we went to the port, Midway Island aircraft carrier, and boarded the aircraft carrier for the first time. We had to sigh at the development of the military industry in the United States. We can imagine that their aircraft carrier was so powerful as early as World War II. Today we can imagine it. China's aircraft carrier has just started, there is still a long way to go! In the afternoon, I went to potato chips mountain on foot. It was so sunny and exhausting! But it's worth it when we get to the scenic spots!
