Just like how this recent outbreak materialised out of nowhere, today’s idiom is about creating something from nothing!
- 无 – Wu2
- 中 – Zhong1
- 生 – Sheng1
- 有 – You3
So 无中生有 can mean to conjure something from nothing, to make up malicious rumours or fake news. Or it can also mean to create something from nothing, to materialise something where there once was none.
Take it however you like, I just like creating stuff.
Conservation of energy side, sometimes something can come from nothing. You just have to dream it into being.
