How it is used
- Used for a product, book, or invention coming out / hitting the market - 这款手机刚问世 (zhè kuǎn shǒujī gāng wènshì) this phone just launched.
- Literally 'to enter the world'; more formal and event-like than 出来 or 上市. Subject is the creation, not the maker.
- Common in journalism and product/culture writing; carries a whiff of 'the world now sees it for the first time'.
