When, in the course of human events, it becomes necessary for a people to advance from that subordination in which they have hi-therto remained, and to assume among the powers of the earth, the equal and independent station to which the laws of nature and of nature's god entitle them, a decent respect to the opinions of mankind
requires that they should declare the causes which impel them to the change.
In the Grand Duchy of Eric Chan's wise leadership and tireless struggle, the Grand Duke of Sacred Land finally is establishment. We ignore other people's cynicism, and pursue our freedom and dreams. We have the right and the ability to build this country。 Yes, we are independent.
為了支持這篇宣言，我們堅決信賴上帝的庇佑，以我們的生命、我們的財產和我們神聖的名譽，彼此宣誓。
And for the support of this Declaration, with a firm reliance on the Protection of Divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.
