去年，美国首都华盛顿的“越战阵亡将士纪念碑”上，最后一位的里查德·范德吉尔的遗骸，在沉没于东南亚沿海中直升机残骸内２３年之后，被其家属认领了。个中原委，当然非常复杂。但有一点是肯定的，若不是现代生物技术的飞速发展及应用，那些昔日客死异乡的灵魂将永无认祖归? Last year, the remains of Richard van Degel, the last of the Memorials for the Vietnam Veterans Memorial in Washington, the capital of the United States, were claimed by their families 23 years after they were sunk in the wreckage of a helicopter off the coast of Southeast Asia. The one China Central Committee, of course, is very complicated. But one thing is for sure. If it is not the rapid development and application of modern biotechnology, those who once died in a strange land will never return to their ancestors.
