Jiang youre quite confused  Where does it say Ive backed off  I cited Fairbanks as a prime example of someone who uses it in the third sense  Youve also quite erroneously mixed up what wikipedia policy says about definitions  The intent is to prevent extremely short articles and for them it suggests that you extend them  It also tries to group very related terms together  Chinese Republic is related to different things depending on the context of where a person might have read about it or what point of view the person is coming from  Republican China for example we agreed to point to History of the ROC since it is most appropriate for someone looking for something about   But for someone who says Chinese Republic means the ROC exactly we cant point him there we have to point him towards ROC  And then theres the third definiton that means something else entirely
