On December 7, 2022, China began to loosen epidemic control, and on December 9, it basically announced a comprehensive relaxation. Then Omikjon began to sweep across the country, especially Beijing in the early days. I am not immune. COVID-19, which has occupied everyone's life in the world for three years, but is still unfamiliar to most Chinese people, has finally become very real. I hereby recorded my own COVID-19 (Omicron) experience. It is perhaps an individual's "small history" amid the country or world's "big history".
