The Shenzhen test acted as both a stress test and a marketing initiative. The City government gave away $1.5 million to 50,000 randomly selected citizens, who each received 200 yuan—about $30—usable at any of the 4,000 merchants who accept the digital yuan. The Suzhou test will include important new features that did not factor into the Shenzhen trials, most notably the ability to pay while offline.
