The photo taken on Feb. 3, 2019 shows One World Trade Center (One WTC) in New York, the United States, with its top illuminated in red. One WTC, the main building of the rebuilt World Trade Center complex in Lower Manhattan, was lit up to celebrate Chinese Lunar New Year. With China in festive mood, cultural activities are being held across the United States. Dragon and lion dances, Peking Opera performances, concerts, fireworks and light shows... a flurry of events in the United States helped people understand the most important festival of China.
