My roommate hates coughing at night.

They are all roommates in the same dormitory, all in other places. They should help each other. How can people eat whole grains without getting sick? Such a thing will happen to them in the future. You can buy him some cough medicine, or you can cook it with brown sugar, ginger and some onion roots. Or add brown sugar and light white wine to white wine, burn white sugar with wine and take it with hot water. Or mashed garlic, with sugar, and drink together. These methods can be used for Liang Yu cough and excessive internal heat cough. You can also accumulate some experience for yourself and do a good job in dormitory relations.
