Translate the letter below. Help me!!!!!!!!!!!!!
My father has an unusual hobby: carving eggshells. As everyone knows, eggshells are very fragile. My dadd can make beautiful pieces of art from empty eggshells. It's amazing! He started the hobby five years ago after a trip to the US where he saw some carved eggshells in an art gallery. My father did not go to class to learn how to carve. He learned everything from the Internet. Some people say that this hobby is difficult and boring, but it isn't. All you need is time. It may take two weeks to complete one shell. I find this hobby interesting because carved eggshells are unique gifts for family and friends. I hope that in the future he'll teach me how to do eggshell carving.
