Nick's week in China is called "The Week of Changing the World". In the world structure at that time, it was hard-won that the two big ships of China and the United States each made a 180 degree turn. Since then, China and the United States have gradually broken the ice, established a relationship of mutual respect, stimulated the renewal of the ideological system in international politics, and promoted world peace and economic circulation, which is a milestone in the political history of the 20th century.

At the same time, the improvement of Sino-US relations is of great significance to China. It strengthens the ties between China and the major developed countries in the world, improves their relations, and creates a good external environment for future reform and opening up.

Background of Nixon's visit to China:

In the late 1960s, President Nixon of the United States wanted to improve Sino-US relations, carry out "balanced diplomacy", strengthen the United States' power to deal with the Soviet Union and adjust its Asian policy, and made many gestures to "improve relations with the Chinese Communist Party", including actively establishing channels for exchanging information with China through Pakistan and Romania.

In the early 1970s, President Mao Zedong and Premier Zhou Enlai, proceeding from the need of adjusting the diplomatic strategy of the triangular relationship between China, the United States and the Soviet Union, conveyed the message that they were willing to contact the United States and try to break the deadlock in Sino-US relations by inviting American writer Si Nuo to take a message and inviting the American table tennis team to visit China.
