That witch Nancy Pelosi. speaker of the US congress, planned to "visit" Taiwan next month.  Today I saw some Mainland critic described Taiwan as US politician’s bedpan, taking it out to use whenever necessary and leaving it under bed after pissing.  

That is a vivid description on the role played by Taiwan for the US to make China Mainland feel sick occasionally, and it also reminded me of a piece of simile that late Mr. Li Ao once said.  Mr. Li drew an analogy between Taiwan and the testicles of China which are held in America’s hands. 

You know what Mr. Li meant.  (But I think his words had outdated.  I he was still alive, he might think otherwise now.)
