On an everyday Tuesday morning, a big crowd has gathered outdoors a grocery retailer in Xuchang, a metropolis of 4m folks. Go to Pangdonglai on the weekend and issues are even busier. Hundreds, some having travelled tons of of kilometres, arrive earlier than daybreak to take their place in a queue that snakes forwards and backwards in entrance of the shop’s entrance. At a time when China’s ritziest purchasing centres are sometimes desolate, and the nation’s economic system is struggling, the success of Pangdonglai’s 13 shops is charming executives who need to perceive shopper sentiment.
