天堂 (tiāntáng) is the standard word for 'heaven' as a paradise after death or a place of bliss (e.g., 人间天堂). It differs from 天上, which means 'the sky above' and is less used for the afterlife, and from 乐园, which can mean 'paradise' but primarily refers to an amusement park (e.g., 游乐园) or a figurative earthly paradise.
