The night on Chang'an Street is so long, is it enough to bury a dream? Lin Yu'an, the restorer of the Forbidden City, was forced to sign a marriage contract and became the caged bird of Shen Yanzhou, an upstart in the Beijing circle. The night she moved into the top apartment on Chang'an Street, she saw the costume hanging in the cloakroom - belonging to Shen Yanzhou's dead Bai Yueguang Ah Ruan, and her face in the mirror was eighty-nine times similar to hers. He took her to and from Chang'an Club and taught her to identify the wolf in the power chess game, but when he was drunk, he stroked her face and whispered A Ruan's name. When she was holding the pregnancy test form and thinking about her future, an "unexpected" miscarriage stained the first snow on Chang'an Street. When they met again in Suzhou three years later, he crushed the sugar painting she had just drawn and said, "Yu'an, you can't escape." The blood letter of life experience revealed a deeper scar: she was actually A Ruan's twin sister who was transferred into a contract, and the scapegoat of Shen Jiazheng's enemies. So she chose the scene of revenge at the tallest tower on Chang'an Avenue, under the spotlight of Shen's listing celebration, and held up the ancestral "Hanshan Picture" to tear apart the truth: "This fake picture has my sister's hair sewn in it!" On the day when the late-stage lung cancer was confirmed, the lights were on in Chang'an Street. She leaned against the floor-to-ceiling window and chuckled: "Shen Yanzhou, scatter my ashes on this street." He tremblingly hugged her cold body, and the traffic outside the window was like a long golden river. The head of the Shen family, who was released from prison many years later, always wandered Chang'an Street at midnight. Some say he is looking for a grain of ashes, others say he is waiting for a dream that will never dawn. Chang'an Avenue can accommodate huge power, but it cannot tolerate a humble dream.
