Hello, I believe the name your teacher gave you should be ""(not) full name ""(millet), which is the plant in the picture.
Thailand is an agricultural country and has a good concept of agricultural products, so many people take the names of plants as their names.
or a cute nickname for us, a very good name, not very common, not rustic, but a name that makes people think that the owner of this name should be cute. Your teacher is so sweet.
