On October 1, 1949, the People's Republic of China was founded. The People's Liberation Army continued to move south. On the eve of the liberation of Guangzhou, the Kuomintang spies fled to Taiwan on the American-made landing ship "Lianrong" and stopped at the inner harbor of Macau on the way. The underground party organization of the Communist Party of China formulated a thorough plan for subversion. The director of the military law department was a spy arranged by the Kuomintang. The captain must execute the order of the commander-in-chief of the navy Gui, otherwise the warship and all the officers and soldiers on the ship will be blown up at any time. The sailors missed their hometown and were reluctant to leave their homeland. The spies killed one to warn the hundred, punished deserters, and angered the sailors on the warship. At this time, Captain Guan's father-in-law and a senior Kuomintang general revolted, putting him in a dangerous situation. He was in a state of confusion and was suddenly arrested by the spies. Our party's underground workers went to Macau in person and worked closely with the underground party members on the ship. With the help of the people of Macau, they mobilized and organized the sailors to prepare for the uprising on the one hand, and rescued Captain Guan on the other. Our underground party members fought a thrilling battle with the Kuomintang spies on the ship with great wisdom and courage, and thwarted the conspiracy of the Kuomintang spies. At the critical moment, Captain Guan recognized the overall situation and resolutely led the officers and soldiers to revolt. The "Lianrong" faced the rising sun, raised the bright five-star national flag in the inner harbor of Macau, and sailed towards the embrace of the motherland with the love of the Macau people for the new China.
