It’s 11 a.m. on a brisk Friday morning. In the middle of a short block of 40th Road, just off Main Street in Queens, where colorful signs stand out against the densely packed four-story buildings, a handful of Chinese delivery workers dismount from their motorbikes. The dry pavement here is a welcome sight; much of the downtown area was buried under a foot of snow earlier in the week. The men, dressed in sneakers, blue jeans and puffy jackets, gather in a circle at one of the few empty parking spots.
