Zibo, an industrial city in eastern China's Shandong province, is known for its barbecue. The city saw its population double during the months of March and April.
On April 29 alone, there were a record 87,000 train tickets purchased for Zibo. Several major cities, such as Shenzhen, Shanghai or even Beijing have announced the end of some restrictions on street stalls in the wake of the "miracle of Zibo" This is an astonishing turnaround. Chinese President Xi Jinping is supposed to abhor this informal economy.
