Nine Quhua Street is the most curved street in the world. It was designed and built to make the busy traffic breathe in the 1920s, but now it is the most attractive street in San Francisco. Lombard Street is actually very long. There is a sharp turn between Hyde Street and Leavenworth Street. There are eight sharp turns. Because there is a 40 degree slope and it is curved like a zigzag, the car can only go down the single line. . The streets are full of flowers, spring croquet, summer roses and autumn chrysanthemums, and the flowers are dotted with flowers. You can also overlook the Bay Bridge and the Coit Tower. If you don't drive, you can follow the pedestrian walks along the flower street to enjoy the beautiful scenery. Flower Street is really a pretty flower, its not difficult to walk around on foot. I dont know how many tourists are there every day, so why are the residents on both sides so calm?
