The magnificent San Francisco City Hall, built in 1913-1915, is a veritable rebirth of the bathing fire, because it is the fifth rebuilt city hall, the first four of which were destroyed in the earthquake and fire shortly after it was built. That's why San Francisco's emblem is an immortal bird, soaring in the rebirth of a bathing fire (see the photo held by the narrator's uncle). San Francisco City Hall is not only free to visit, but also free to explain three times a day at 10:00 12:00 and 2:00 p.m. The uncle who explained to us is a volunteer. He has explained here for 19 years. His knowledge is very rich and enthusiastic. The history and current situation, design and style, function and use of San Francisco City Hall are very interesting and knowledgeable. I met a couple of couples and got married there. A Chinese girl and a Jewish young man were very similar to Facebook founder Zuckerberg and his Chinese wife Chen. They shared the happiness of the most beautiful moment in their lives and sincerely wished them happiness.
