My great grandmother told me how to handle changes in weather when I left for university studies in Africa. She said if the weather is hot, I must drink cooling tea. She packed for me some Wang Lao Ji for me to drink during hot season. She said if the weather is cold, I must know how to eat to strengthen my 'Qi'. She said I can eat some mutton or dog meat soup. So everytime when I went back from Africa to China, she will slaughter sheep to boil soup for me to drink.
