1. Go to the hospital. 2. Take some medicine, preferably lozenges. 3. When I had a bad throat before, I had a secret recipe: if possible, find a tin bucket and a piece of better charcoal (it’s best to go to the countryside to find it). Burn the charcoal until it is bright red, then suddenly pour ice water over the charcoal and pour it into a bucket. Then drink the stuff in the bucket~~ (Be sure to drink it while it's hot) This is called burning slag water. If an opera singer has a throat problem, drinking it is very effective. 4. Drink the batter. It's made by boiling glutinous rice into a batter, preferably the crunchy kind. Keep it in your throat and insist on not singing for a month to ensure that your voice is good (there is a singer in my country who is the best in Henan opera, named Ma. She had a reversed voice when she was young, and she used this method to cure it).
