Cách sử dụng
The expression "insist on doing" means to demand or require that something be done in a particular way, even if other people don't agree or think it's necessary. It is used when someone wants to do something and won't change their mind even if others object. For example, someone might insist on having their coffee a certain way, or on taking a specific route home from work. It is important to use this expression politely, and to listen to others' opinions even if you ultimately decide to insist on your way of doing things.
