Cách sử dụng
"Birch" is a kind of tree with a smooth, white or silver-grey bark. The word can be used in different ways. For example, you might say "I saw a birch tree in the park" or "This furniture is made of birch wood". In some cultures, people use the branches of the birch tree to make a kind of switch or whip for punishment. However, this is not a common use of the word in English, and it is generally seen as negative or outdated. So, if you want to use "birch" in a positive context, it is better to focus on the tree or its wood.
