Visitors, born in 1980s and 1990s, swarmed into the children’s park at Hangzhou Youth & Children’s Center last Saturday to experience their childhood memories once again. Built more than 30 years ago, this park plays a special role in the heart of many Hangzhou citizens. Rocket to the Moon, Mini Zoo, Naughty Castle, Frog Jump… these old, classic recreation facilities have offered great memories for generations of Hangzhou citizens.
