Workers collect ice blocks from the frozen sea in Dandong City, Northeast China’s Liaoning Province, Jan. 16, 2017. The ice blocks collected in Liaoning’s coastal areas are used for preserving sea food, a practice that dates back 100 years. About 700 ice-collecting devices can create 700,000 ice blocks a day, generating a total output of nearly 200 million yuan ($29 million) in one month. (Photo/CFP)
