Its closest alternative in terms of meaning could be the term "jiangshi", which is a Mandarin word that translates to "stiff corpse". This term refers to an undead creature that hops around and attacks its victims, much like how vampires do in Western folklore. While "chirico" does not have any direct synonyms, there are plenty of other words related to vampires or the supernatural, such as "bloodsucker", "undead", or "nosferatu", that may be used in their place depending on the context of the sentence.
