Lin, director of the Department of Ophthalmology and Nose of the First Affiliated Hospital of Chating Street, looks very good. If it's not serious, you can go to the drugstore and buy a nasal spray called Yizhi Ecological Liquid, which is Miao medicine. The effect is very good. I just sprayed this, and it's not expensive. 42 yuan bought a bottle since. If there is inflammation, roxithromycin and thick nasal sputum tablets can be added.
