During the 1971 World Table Tennis Championships in Nagoya, American athlete Glenn Cowan accidentally boarded the Chinese team bus after missing his own. At the height of the Cold War, when diplomatic ties between China and the United States were nonexistent and people-to-people exchanges were rare, the atmosphere was heavy with tension.

In a moment that broke the ice, Chinese athlete Zhuang Zedong stepped forward to greet Cowan. He offered a warm handshake and presented him with a silk tapestry featuring the Yellow Mountains. This simple yet historic gesture became known as Ping-Pong Diplomacy, helping to pave the way for the normalization of relations between China and the US.
