On Feb 21, a special Chinese “diplomat (外交官)”, Bao Bao the panda, arrived in China from the United States. Many people in the US found it hard to say goodbye to her and were at the airport to see her leave.

Bao Bao was born at the National Zoo in Washington DC in 2013. Her parents are Tian Tian and Mei Xiang. They went to the US in 2000. “We have watched Bao Bao grow up during the past three years,” said Dennis Kelly, the zoo director. “We’re going to miss her so much.”

In fact, the zoo has been preparing for Bao Bao to leave since the moment she was born. That’s because under the agreement between China and other countries, all the pandas born outside China must return home by the time they are four years old.

The flight took nearly 16 hours. A zookeeper and a doctor were on the plane together with Bao Bao. To make her comfortable, the zoo put bamboo and other snacks on the plane. Now, Bao Bao is at her new home in Chengdu. She will start a new life there.

Back to 1972, China first sent two pandas to the US as gifts. Right now, four zoos in the US have pandas from China. The pandas play an important role in the friendship between the two countries.

Of course the US is not the only country with pandas. There were 44 pandas living in different countries around the world last year, reported Xinhua.
