没有哪一次巨大的历史灾难不是以历史的进步为补偿的。——恩格斯旅顺口,一个历经沧桑的海军基地。一百多年来,它经过了日本侵略、中国赎回、沙俄强租、日俄争掠、日本占领、中苏共用、接收回归七个时期,这在世界海军史上实为罕见。这里至今保留着近代战场的遗址,那肃穆的山峦、残存的炮台、堡垒、墓冢、石碑,伴着阵阵阴凉的海风,似乎都在向人们诉说着往昔岁月的一切…… No huge historical disaster is compensated by historical progress. - Engels Port Arthur, a vicissitudes of the naval base. For more than a hundred years, after seven years of Japanese aggression, Chinese redemption, strong rent of tsarist Russia, rivalry of Japan and Russia, occupation of Japan, sharing of both China and Soviet Union, it was rarely seen in the world naval history. It still retains the ruins of a modern battlefield so far, and the solemn mountains, remnants of forts, fortresses, tombs, stelae and cool sea breezes seem to be telling people everything from the past to the present.
