Recently, the flu has been severe. A teacher's friend said many children in the class are on leave.

I recommend a small trick for children with cold and cough, which is also a traditional remedy that elderly people know.

Bake the oranges until the skin turns black and they emit heat from the inside out. After cooling, peel them and eat directly.

⚠️⚠️ Attention, this is only suitable for cold and cough; don't get it wrong.
