Some lucky New York City commuters will soon have the chance to trade their city subway rides for free rides on the metro in Hangzhou, China!

Here’s a little something I’ve gotten from my email bag. To help promote this city to American visitors, Hangzhou Tourism Commission is holding a contest with the change to win round-trip flights for two between New York City and Hangzhou.

To further publicize this contest, the commission has branded 20,000 NYC MetroCards, which will be sold at 42nd Street–Grand Central Terminal and Fulton Street – World Trade Center subway stations.

To register for the contest, visit www.hzgoldenticket.com. The first 100 people to register will have the opportunity to receive a “golden ticket” by mail. The “golden ticket” provides them two free NYC subway rides but can also be exchanged for a Hangzhou MetroCard good for free rides on the subway in Hangzhou. The contest ends midnight May 31, 2018.
