While families reunite for the Chinese New Year, many workers stay at their posts instead of going home. Utility workers inspect 11.75 kilometers of cable tunnels, 10 meters underground in Xiong'an New Area, using intelligent robots to ensure the power supply remains safe. In Jiangsu, teams work around the Spring Festival holiday to rebuild 1,053 km of 500-kilovolt power lines above a major highway. Railway staff climb steep cliffs during short maintenance windows to check and remove dangerous rocks, keeping railways safe for millions of travelers. These heroes work in the hardest places so everyone else can enjoy a warm, peaceful holiday.
