In April 2017, two giant pandas from China arrived at a zoo in the Netherlands. There, they were welcomed to the Chinese-style compound where they were to live. On 30 May, after the preparations were complete, the day finally came when the pandas met their fans for the first time. People were excited – the zoo is the only place in the country where it is possible to see pandas. In fact, the last time there were pandas in the Netherlands was in 1987. And of course, the main reason why they were so excited is that pandas are just so cute!
