Sorry, I should have translated to English on my post. Google translate is good enough for this short paragraph, as it was written in very formal Chinese.
here we go, google translated:
"People's Republic of China
In February 1950, the Chinese government and the Soviet government signed the "Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance" on the same day, and signed the "Agreement on China's Changchun Railway, Lushunkou and Dalian." The agreement promised to withdraw from Lushunkou at the end of 1952, and as the Korean War broke out, the situation in the region became increasingly tense. At that time, the Chinese Navy did not have the power to guard Lushun Port. On September 15, 1952, the Chinese and Soviet governments exchanged the "Exchange of Letters on the Extension of the Term of the Joint Use of China's Lushunkou Naval Base." In 1954, Soviet leader Khrushchev decided to return Lushunkou to China. At the beginning of 1955, the handover began. In China, the Navy’s Lushun Base was established. In May, the two countries completed the handover, and at the end of the month, 120,000 Soviet troops withdrew [3].
Before 1960, it was a big city. On January 18, 1960, the State Council of China withdrew Lushun City and set up Lushunkou District [4]. After the city of Dalian was changed to Dalian, it still belongs to it. At that time, there were three roads connecting Dalian."
