First patient helps capital get jump on coronavirus

Since the cluster of novel coronavirus infections emerged in Beijing last week, one local man has become well-known－not only because he was the first confirmed case in this outbreak but also thanks to his great memory, he has contributed much to narrowing down the sources of infection.

The man, surnamed Tang, 52, has reported every place he visited since May 30 and provided a list of 38 people with whom he had close contact in the two weeks before he was diagnosed with the disease on June 11.

Tang has been praised as having "the most powerful brain" by netizens.
