I'm not sure what you mean by "yinsewangchao". This doesn't appear to be a common word or phrase in English or any major language I'm familiar with. It could be:

1. A name or term from a language I don't recognize

2. A typo or misspelling of something else

3. A made-up word or code

Could you please provide more context or clarify what you're trying to ask about? If it's a specific term, perhaps you could explain where you encountered it or what field it might relate to. This would help me understand and provide a more accurate response.
