The night of yesterday. I share my article about mosquito in WeChat group, There had two foreigners replied me . Have a foreigner asked me , “Can you get malaria from mosquito in China?”, I don’t understand the “malaria” mean, so I went to check , then I get a new word. When I answered his question , I just used four words , don’t have care in term of grammar question. I also found they don’t care about grammar when they speak.
