Cleaners' firecracker plea lights up Internet

An online picture of two street cleaners asking for fewer firecrackers to be set off during Spring Festival has triggered widespread interest.

The married couple, wearing their orange work outfits, were photographed standing in a street holding a heart-shaped card asking for young people to cut back on the number of firecrackers to enable the couple to return home earlier.

Their message ends with the words, "Thanks for your understanding."
