求教，状语从句

semis

请教个句子：The Forbidden City in Beijing, from which the emperors ruled by heavenly mandate, was a site which no commoner or foreigner could enter without any permission, on pain of death.

如果状语从句还原应该是：the emperors ruled by heavenly mandate from forbidden city或者The empr ruled from the forbidden city by heavenly mandate ？

如果是第2种方法，by heavenly mandate是不是距离empr太远了？
