Reading carefully, the history of Lushun Port is actually the epitome of modern Chinese history. From Russia to Russia, Japan to Russia, the War of Resistance Against Japan to "one-sided", according to Shen Zhihua's research results, even the outbreak of the Korean War and the handover of Lushun Port by the Soviet Army to China are all related. When I arrived at the Military Port of Lushun, I saw it with my own eyes. I felt that this place was really unusual. It was surrounded by hills. There was a natural harbor in the middle, which was easy to defend and difficult to attack. No wonder 20,000 Japanese died in battle and took Lushun Harbor from Russia. Our warships and submarines are now moored in Lushun Harbour. Many surface ships could be seen from the port, but the submarines were blocked. The Military Port Park is the best place to watch the 300-metre-wide mouth of the harbour leading to the Yellow Sea. Finally, no tickets are required to visit the Military Port Park.
