Pillars symbolizing a united nation of 56 ethnic groups stand in Tian'anmen Square in Beijing yesterday. The pillars, 13 meters tall and weighing 26 tons, are part of the decorations for the 60th anniversary of the founding of the People's Republic of China. Each features an engraved image of an ethnic group in its traditional costume. Beijing also tested thousands of landscape lights last night for the first time. The display involved decorative lights on more than 30 overpasses and 150 buildings along Chang'an Avenue, the major thoroughfare in Beijing, which runs partly along Tian'anmen Square. [Xinhua]
