Comparing "li" and "cong"

Both 离 (lí) and 从 (cóng) can be translated into English as “from”. In Chinese however, their meanings are different. 从 is used in cases where the subject's position relative to a fixed location changes. 离 expresses a “static” distance, or a distance that is unchanging. Both can be used in defining distance or time, however 从 has more meanings than 离.
