It is a much-acclaimed fact of history that overseas Chinese furnished arms and ammunition to assist Dr. Sun Yat-sen with the revolution that toppled the Ch'ing Dynasty, which shows that emigration does not reduce national power. On the contrary, helping emigrants to gain a footing for themselves overseas is an extension of national power.
清末華僑購買武器，幫助國父孫中山先生革命的史實，一直傳為佳話，由此也可見，移民不會削減國力，若能提供助力，幫助他們在海外立足，反而是延伸國力。
