Translation:The treatment for flu can be done at home.
FLIP FLOP on the sentence with flu and house. One thing in multiple choice, another here. It would be nice to be introduced to variations in Tips and Notes than whatever the hay this means: "chú ý classifier được dạy kèm từ vựng chỉ bộ phận cơ thể - ckhadung" Why not put it in Mandarin, Japanese and Korean dialects while were at it? They would be equally so helpful for a course labeled "Vietnamese for English."
