"The light show was excellent. It offered a chance to learn more about Chinese culture," said Mark Brennan, a tourist from Ireland, under Dubai's iconic Burj Khalifa, which was illuminated in "China Red" to send warm greetings to the world.

Brennan was among the thousands of spectators who witnessed the laser light show on the world's tallest building on Jan 29. The show, which ran for two days, celebrated one of China's most significant festivals - Spring Festival.

During this time, many towers and skyscrapers worldwide were simultaneously illuminated with red lights in response to an invitation from the Shanghai municipality to commemorate the first Spring Festival since UNESCO listed the celebration in its World Cultural Heritage inventory.

The initiative received active support from the World Federation of Great Towers (WFGT) and the Council on Tall Buildings and Urban Habitat (CTBUH).

Skyscrapers and landmark buildings in locations including New York, Chicago and Dallas in the United States, Vancouver in Canada, Singapore, Tokyo in Japan, Dubai in the United Arab Emirates, Barcelona in Spain and Bucharest in Romania all participated. Some locations also hosted special activities to celebrate the festival.
