HONG KONG — More than 10,000 people marched in Hong Kong on Sunday to press for open elections in 2017, staging the first mass rally since police cleared pro-democracy demonstrators from the streets in December.Protesters rallied in the financial district known as Central, and the prop that came to define the fall 2014 protests -- the canary yellow umbrella -- was ubiquitous, despite there being nary a threat of rain. But Sunday's mood was perceptibly muted.
