Cách sử dụng
The expression "have back" is used to mean to get something that you had before, but was given or taken away temporarily. For example, if you lent someone your book and now you want it back, you can say "Can I have my book back, please?" or if someone borrowed money from you and you want to get it back, you can say "I need to have my money back now." It is a polite and straightforward way of asking for something that belongs to you.
