LJUBLJANA, May 19 (Xinhua) -- Tens of thousands of Slovenian secondary school students in 20 towns on Friday took part in the traditional quadrille dance, which has gradually became a national cultural heritage, the Slovenian Press Agency (STA) reported.
The tradition of mass quadrille dancing dated back to 2002 and was initiated in Maribor, the country's second largest city, and the graduation celebration aimed to promote zero tolerance to alcohol and illicit drugs.
The graduates in the capital city of Ljubljana were greeted by President Borut Pahor, the STA report said.
This year's mass dancing event was joined by 54 towns in seven countries, according to STA.
Since the annual parades first started in 2001, more than 300,000 students in 100 cities and 10 countries around Europe have taken part.
The parades have set nine world records for the largest number of simultaneous dancers of the quadrille.
