Busy: having a lot to do and little free time. Like other Chinese adjectives it needs no 'to be', usually 很 instead: 工作很忙 'work is hectic'. 你忙不忙？ asks 'are you busy?', and 帮忙 (bāngmáng) is 'to help out'.
Bận, bận rộn: có nhiều việc phải làm, ít thời gian rảnh. Giống tính từ tiếng Việt, không cần động từ “là”, thường thêm 很: 工作很忙 (công việc bận lắm). 你忙不忙？ là “bạn có bận không?”; 帮忙 (bāngmáng) là “giúp một tay”.
