Exploring the JD Electronics Super Experience Store in Hefei
Recently, I heard that JD’s second global electronics super experience store opened, and it’s right here in Hefei. After a quick search on the map, I found it’s not too far away, just five subway stops or about a ten-minute bike ride. Exiting the subway, from a distance, you can see a giant “JD Dog” (JD’s mascot, a dog, colloquially called “Dog East”) “climbing” the glass walls of the store. Since it’s still in its trial operation phase, you can spot some construction ongoing. Fortunately, the inside of the store is almost fully operational.
