DBE is a British honour. The letters stand for Dame Commander of the Order of the British Empire. When the British state wants to thank a woman for work that matters to the country — music, science, charity, public life — it may give her this title. After that, people may call her Dame plus her name, instead of Mrs, Miss, or Ms. A man at the matching rank becomes a knight and may use Sir. Though actually, British Empire is a name from an older time; the honour still exists, but the empire it names does not. You will meet this in news about famous British women. It is formal, ceremonial English, not something people in Taiwan put after their own names.
