Bradbury building, built in 1893, has hidden hidden mysteries in the common outdoors, such as transparent patio, exquisite forged iron staircases and elevators, plain brick carvings, gorgeous lights, calm, atmosphere, mysterious, quiet, noble buildings that make people appreciate and have infinite reverie... Come in from the hot and noisy streets outside, to quietly hold their breath, on the one hand, it is shocked by its beauty. On the other hand, it seems as if it suddenly broke into a Hollywood film showing the scene of the 1930s.
