Existence is also conveyed: (1) by verbs marked with 着 zhe, which not only indicates the existence of something but also highlights the way or manner in which it came to exist; or (2) by verbs (usually followed by direction indicators) marked by 了 le to indicate a completed action which has brought about the appearance (i.e. coming into existence) or disappearance (i.e. going out of existence) of something or somebody. These sentences follow the pattern of time or location word (or expression) + verb + noun, though location rather than time is the more common reference with verbs marked by 着 zhe.
