When you mention San Francisco, what do you think of first? I think many people, like me, will think of the Golden Gate Bridge. Don't just take it for granted that the Golden Gate Bridge is golden, but actually it is vermilion. The name was taken by John Fulimont, an American writer and explorer of the 19th century. Because when he first arrived in San Francisco, he entered the San Francisco Bay from the Pacific Ocean, and saw the entire port gleaming under the sunlight, like the "Golden Gate", so the bridge across the harbor was of course called for the "Golden Gate Bridge". Such an iconic attraction is unavoidable popular tourist place, and it is also a must-see for everyone on their trip to San Francisco.
