Dongguan has a rich historical heritage. Sea Battle Museum is one of them. It is a bridge connecting the past with the future. In this museum, many precious artifacts and documents are displayed. They tell the history of the Opium War. Our hero, Mr. Lin Zexu, destroyed the opium and defended against the attacks. He is well-known for his determination, courage and success. The museum is a remembrance of a suffering and humiliating period. When I walk in it, I feel the pain and misery. When I stare at Lin Zexu’s statue, I seem to see how he bravely protected our homeland. For a nation to be in control of its fate, its people must possess wisdom and courage to get rid of such corrupt thoughts to survive and thrive. In a word, Sea Battle Museum is not only a treasure for Dongguan, but also a fortune for all humanity.
