In 1894 when the Revive China Society was formed, Sun only had two principles: nationalism and democracy. He picked up the third idea, welfare, during his three-year trip to Europe from 1896 to 1898. He announced all three ideas in the spring of 1905, during another trip to Europe. Sun made the first speech of his life on the "Three Principles of the People" in Brussels. He was able to organize the Revive China Society in many European cities. There were about 30 members in the Brussels branch at the time, 20 in Berlin, and 10 in Paris. After the Tongmenghui was formed, Sun published an editorial in "Min Bao" (民報). This was the first time the ideas were expressed in writing. Later on, in the anniversary issue of "Min Bao", his long speech of the Three Principles was printed, and the editors of the newspaper discussed the issue of people's livelihood.
