Teacher, it is said that men born on May 1st cannot get married. Is it true?/You don't say.

This should be some feudal superstition. Whether you can marry this man depends on his three views and his fit with yourself, and nothing else needs to be considered. If you know through communication that his three views are the same or almost the same as yours, and there are still some hobbies in your daily life that are in tune, why not marry him?

Love and marriage are based on feelings. Two of a kind, mutual love and respect are the basis of feelings. So if you have such a foundation, you can consider marrying him, because such a predestined relationship is hard to meet.
