Aerial photo taken on Feb. 11, 2021 shows ultra-high voltage (UHV) power transmission lines near Xilingol ±800-Kilovolt convertor station in north China's Inner Mongolia Autonomous Region. All 59 workers of the convertor station chose to stay put to celebrate this year's Spring Festival at the grassland. On the eve of the Chinese Lunar New Year, about 20 employees stuck to their posts, while those who took a break made dumplings and decorated the convertor station with paper-cutting decorations and couplets.
