1 . These years some pandas from China are taking their special vacations in some other countries. They will get back home at the planned time. But this May, two pandas living in Canada had to get back to China before their vacation really ended.

The two pandas were happy to live in the Calgary Zoo in Canada, but when COVID-19 broke out (爆发), there was problem—it was difficult for the zoo to get them enough bamboo (竹子).

Er Shun and Da Mao arrived in the Calgary Zoo in 2018 after spending five years in their first home—the Toronto Zoo. They were to live in the Calgary Zoo until (直到) 2023. Over the difficult times, there were no flights from China to Canada, so bamboo from China couldn’t get to Canada by plane. The Calgary zoo tried to get bamboo from the U.S to feed the two pandas, but they said the pandas didn’t like to eat it at all. In the end, they had to ask China for help and decided to let the pandas go back home early.

The two cute pandas were the stars in the Calgary Zoo. People in Canada liked them very much. Many of them weren’t happy to see the animals leave. But in China the pandas can get enough bamboo to eat. The Calgary Zoo had to do this.
