Hong Kong, Aug 07: A 120,000 US dollar public toilet complete with television has opened for business in Beijing's Tiananmen Square, a news report said today. The luxury loo also boasts piped music and a computerised system which tells people whether it is engaged or vacant, according to the report. The toilet is sited on the east side of the square, the scene of the Tiananmen Square massacre in 1989 when hundreds of students were killed after troops marched in to end a demonstration.
