When it's winter in the R.O.C., it's summer in Malawi, right at the height of the malaria season. So unless you've taken full precautions and are on important business that simply has to be taken care of, it's not a good idea to run the risk of going there then.
這麼「不友善」的警告其實並無惡意，因為我們的冬天，就是馬拉威的夏天，正是瘧疾當道之際，除非有萬全準備和非去不可的要務，否則不宜冒險。
