The existing points and lines would form a closed geometric shape. If we put the new point Z outside the closed geometric shape at first and later then found that the point Z has neighboring relationship with the existing point A which is inside the closed geometric shape, we could not link point Z and A directly because that would bring line crossing. If we rearrange the point Z into the closed geometric shape, that also would cause a lot of work to do. With the help of Exclave, all problems could be solved easily. We use point X outside the closed geometric shape as the Exclave of the point A. Then the line between point Z and X could demonstrate the neighboring relationship of the point Z and A.

原有的各点和相邻线段往往会形成一个封闭的几何图形，如果我们把新增点 Z 设在原有的封闭几何图形外部，后来又发现该点 Z 和位于封闭几何图形内部的点 A 存在相邻关系，这时不能直接将两点连接因为那将产生交叉，而如果将点 Z 重新设在封闭图形内部也将导致大量的调整工作；此时借助外飞地的概念，可以轻松地解决上述问题，即在封闭几何图形外部设置点 X 作为点 A 的外飞地，两点使用同样的颜色，用点 Z 和点 X 的相邻线段表示点 Z 和点 A 之间的相邻关系。

Economy determines ethic only in the final analysis and if we make economy as the ethical starting-point it will inevitably get rid of the humanity nature of ethics and make the subject free of moral responsibility and bring about economical conciliarism. Although convention has same origins as ethics in etymon, content and function, it's difficult for it to qualify as the ethical starting-point for it lacks the spiritual essence that ethics has. Religious love-knot of ethics is just an artificial ultimate hypothesis of the rationality of value, but the religion's nature of inversion of man and God make it unable to be the ethical starting-point.

经济只是在"归根结底"的意义上"决定"伦理，若把经济作为伦理始点必将抹煞伦理的人文本性，消解主体的道德责任，导致经济至上主义；习俗尽管在词源、内容、功能上与伦理有诸多渊源，但由于习俗缺乏伦理的精神内涵而难以成为伦理始点；伦理的宗教情结不过是对价值合理性的虚拟的终极设定，宗教人神倒置的本质决定它无法成为伦理始点。
