The Pacific Exchange: China & US Mail exhibition opened at the Smithsonian's National Postal Museum in Washington on March 20, 2014, aiming to tell the story of the Chinese-US relationship.

Featuring the stamps and mails exchanged between the two countries from the mid-19th century to the 1980s, most of the items on display were carefully selected from the international collection of the museum and are shown to the public for the first time.

Chief curator Cheryl R. Ganz explains that the museum took three years to prepare the exhibition and received a warm welcome from visitors.

"I think for the museum, this is the first time we have done a major China exhibit. I think we are ready. The attendance has been fabulous. People really are interested in this. "
