Cách sử dụng
The expression "by hand" means doing something manually or without the use of a machine. For example, writing a letter by hand means writing it with a pen or pencil instead of typing it on a computer. This expression is often used in situations where precise or delicate work is required, such as drawing, painting, or crafting. It can also refer to performing tasks that were traditionally done manually before the advent of modern technology, like washing clothes by hand or chopping wood by hand.
