Hello. The weather is getting colder. I suggest you drink black tea. For example, Jin Junmei. Cinnamon, dahongpao. Yashan race. Wait a minute. These are all black teas. Black tea has the function of keeping out the cold and warming the stomach. You can add 1 brown sugar to drink black tea. You can also add 1 minute milk powder or milk. The feeling of harmony will be better in this way.
