To welcome the upcoming Dragon Boat Festival and Children's Day, Harbin Polar Park in Harbin, Heilongjiang province, debuted an upgraded underwater show with a brand-new lineup and original high-difficulty movements.

Five underwater dancers unfurled giant butterfly wings in the depths of the ice sea, dancing together with mermaids to showcase underwater ballet, synchronized swimming, and body art.

The park has also launched a series of themed activities, such as the children's painting that kicked off on Tuesday with 100 children depicting their imagined polar world with colorful strokes on a giant canvas.
