Beggar

You may argue not all changes are from within.

True. Unfortunately, another romantic idea that many of us hold, again as a result of reading too much Jin Yong (金庸), is that the Beggar Party (丐幫) represents a major political force, and people could change the history by loudspeakers.

For example, did Sun Yat-Sen lead the revolution by making public speeches and demonstrations? Of course not. To the contrary, he made alliance with many rich Chinese millionaires and organized a series of unsuccessful attacks. (One of his major supporters was Charlie Soong - the father of Soong Ching-ling.)

In fact, many would believe Sun just boasted and did not do very much in material. The Wuchang Uprising (武昌起義) was actually led by Li Yuanhong (黎元洪) - when Sun was staying in Denver of America.

It was a change from within after all.

PS. The simplest way to change the history is to be the historian yourself. That's another story.
