The San Francisco peninsula is a city that is perfect for hanging out. Walk in the north beach of Italy, you can meet the dream cafes in the corner, or walk into the bustling and bustling Chinatown, and feel the old style of the different ethnic groups of different cities. In smaller cities, people and time will be more calm. The size of San Francisco is not too big or too small, but after all, you can choose a region and let yourself sink into it for dozens of hours. Nine Quhua Street is very close to our hotel. After breakfast in the morning, we can walk in 15 minutes. But it is really cumbersome to climb a steep slope. The roads in San Francisco are a big challenge for those who walk, especially for those who drive. Jiuquhua Street is located on Lombard Street in San Francisco. It is the section between Hengde Street and Leavenworth Street. It is the most curved street in the United States. There are 8 turns in a short section of the road, which is a test of driving skills. It is often seen that the car is connected end to end, and it has become a famous attraction in San Francisco. This road has a 40-degree slope, very steep, west high and low east, the car can only be single-line, from the west side of Hyde Street, from the east of Leavenworth Street. Because the flower street is high in the west and low in the east, it is only in the morning that you can see the sunny side. Basically, there will be very few tourists before 10 o'clock. After 10 o'clock, it is very difficult to take photos of people without heads.
