This beautiful street, known as "Jiuqu Flower Street", is famous for its winding and tens of thousands of tourists drive to it every year. It happens to be near the hotel in San Francisco, so it goes to Jiuqu Flower Street twice. This is the most winding street in San Francisco, and it is also famous for the large number of precious flowers planted on both sides of its road. The street was originally a direct road on the Russian mountains, but because of its steep and dangerous conditions, it was eventually converted into nine S-shaped routes and paved new roads with bricks, which made it one of the stars of the San Francisco Highway.
