The Smithsonian's National Zoo in Washington host a six-month celebration of the 50th anniversary (周年纪念日) of the arrival of two giant pandas, celebrating the close cooperation(合作) between China and the United States on panda conservation(保护).
"We are going to have six months of celebrations both online and at the zoo. People can come to see the babies and the mom and dad," Brandie Smith, director of the national zoo said. Annalisa Meyer, the zoo's deputy(副的) director of communications, said the zoo will hold online events, as well as on-site (现场的) events on April 8 and 21. Also on April 16, from 9 am to 2 pm, visitors can enjoy lion dance shows, panda-shaped Bao buns (包子) and calligraphy (书法) shows. They also can speak with the zoo's scientists who study giant panda biology.
The first pandas from China in the US — Ling Ling and Hsing Hsing — arrived at the Smithsonian's National Zoo on April 16, 1972.
In 1972, then US president Richard Nixon and first lady Pat Nixon made a historic visit to China. On their second day in China, the first lady made it clear that she wanted to go to the Beijing Zoo to visit pandas. At a dinner before they left China, Premier (总理) Zhou Enlai told Pat Nixon that China would present the US with two pandas.
The COVID-19 pandemic (疫情) has created difficulties for in-person communications.
"Usually we go to China several times a year, and our colleagues (同事) are trying to come here to visit us. With the pandemic, it's been hard because we haven't been able to see each other in person, but the good thing is that we still have emails, video calls and other ways to communicate," Smith said. She said she hoped the program could last for at least another 50 years.
