Instead of shrieking at the sight of rats in the NYC subway, Chen Yang said she silently reads books at the library of Guangzhou's Panyu Square Station.

The Guangzhou resident found an echo in the tweet of Danny Haiphong, an activist and writer who posted two photos of the NYU subway and Guangdong subway on Tuesday and tweeted that "Train station in Guangzhou, China versus train station in New York City, USA."

The tweet went viral and received thousands of comments, likes and retweets. It also attracted attention of many Chinese netizens and some Chinese media.
