一部中国海防史,就是中华民族百年兴衰史。从19世纪中叶到新中国成立,帝国主义列强80多次从海上入侵,几乎所有的港湾都悬挂过侵略者的盗旗,几乎所有的岛屿都惨遭列强铁蹄的践踏。历史雄辩地证明,国家的发展、和平的维护,离不开强大的海防。21世纪是海洋的世纪,中国有国无防、有海无疆的时代已一去不复返了,让我们再次把视线聚焦到东海、南海这一片深蓝…… A history of coastal defense in China is the history of the rise and decline of the Chinese nation for a hundred years. From the mid-19th century to the founding of New China, the imperialist powers invaded by sea more than 80 times. Suspension banners were invaded by almost all harbors and almost all the islands were trampled upon by the mighty powers. History has eloquently proved that the development of the country and the safeguarding of peace can not be separated from the mighty Haiphong. The 21st century is the century of the sea. The time when China has no defense and there is no sea and sea is gone. Let us once again focus our attention on the dark blue of the East China Sea and the South China Sea.
