As the "Beat Generation" still has the vitality sign, the first "light of the city" in the United States dedicated to the sale of paperback books has been declared the No. 228 landmark building by the San Francisco government. With the protection of the government, I think that no matter how the times change, it will always stay quietly on Columbus Avenue in San Francisco, opening a door to retrospective memories. Come here, standing outside the glass window, the famous "on the road" is in front of me, looking at the handsome face of Kairuyak on the cover, remembering his sentence "I am still young, I am eager to get on the road", The excitement that I can't restrain in my heart began to rise slowly. The bookstore is not big. There are three floors and the top floor is sealed. The two-storey bookstores are tightly packed with books. Under the warm yellow light, two white-haired old people sat on the bench, quietly reading, and talking softly from time to time. The tourists from all over the world come to an endless stream. People shuttle, read, and take pictures in the bookstore, but they are as quiet as holding their breath, only to hear the shutter sound that occasionally rubs and rubs. In this small bookstore, everything in front of me makes me really feel the temperature of culture. When I left, I didn't take any books, but I couldn't help but sing the song: "Goodbye, Jack, goodbye to my Kerouac~"
