Li Guo was awakened by a quarrel early in the morning and opened his eyes in a daze. A lot of memories that did not belong to him flooded into his mind - he had traveled through time and replaced a young man with the same name, and now he was a young man living in a courtyard in 1970. My father was a senior engineer at a steel rolling mill and ran away to the desert. My eldest brother went to the Corps a few years ago and never came back. Taking another look at the neighbors around him, the white eyes he used to have are now about the same age as him. I heard he wants to learn to play movies these days.
