And before we wrap up, let's take you through what's trending across China. Farewell to old cash! The People's Bank of China announced that the majority of the 4th edition of renminbi notes will no longer be in circulation from May 1st. The set of paper notes printed from 1980 to 1990 is familiar with Chinese people now aged between 30 to 60. But the lowest denomination notes will still be in circulation.

Check out the paint job! Xiamen Airlines has sent this unique plane to the skies. This Boeing 787 Dreamliner is the world's first aircraft bearing the United Nations' Sustainability Development Goals on its livery. The newly painted jet is part of a cooperation deal the airline signed with the UN last year to promote the world body's messages globally. The Dreamliner will soon operate long-haul flights to the US after plying China routes for a few months.

And this next one also flies high in the skyb, ut involves flocks of birds! Hundreds of thousands of birds are making their way from various parts of south China to build nests in the north. There, the birds will find a mate to produce offspring. To rest, the birds usually make a stop at nature reserves during the long distance trip, creating an exciting scene for birdwatchers.
