Cách sử dụng
The expression "on the back of something" means that you are relying or benefiting from something else. For example, if a company reported huge profits "on the back of" a new product launch, it means that the profits were made possible because of the success of the new product. Another example is if you say "I made it to the top of the mountain on the back of my friend's encouragement", it means that you were able to climb the mountain because your friend supported and encouraged you. It is often used to show that success or achievement is due to an external factor or support, rather than individual effort alone.
