More than 500 workers began turning the Tian'anmen Square into an Olympic and revolution-themed party venue on Tuesday night ahead of National Day on October 1, which marks the 58th anniversary of the founding of the People's Republic of China.

A total of 400,000 flower and plant pots will be used to decorate the square in downtown Beijing, and scale models of the Acropolis in Athens, the Great Wall and the Olympic torch will be constructed, similar in style to last year's replicas of the Potala Palace and the Three Gorges Dam.

According to the Municipal Bureau of Landscape and Forestry, a central flower terrace, surrounding a fountain, will depict four Chinese characters that read "Wan Zhong Yi Xin", meaning "millions of people, one mind".

A flower terrace on the western part of the square will feature models of the Temple of Heaven and three scenes marking key moments in the history of the Communist Party of China: Nanhu Boatin Zhejiang, on which the first CPC national congress was held in 1921, the venue of the Zunyi Meeting held during the Long March in Guizhou Province in 1935, at which the leadership of Mao Zedong was established in both the Party and the Red Army, and the Yan'an Pagoda in Shaanxi Province, the key landmark in a city that became known as a Chinese revolutionary base from the mid-1930s.

The display will remain in place for the opening of the 17th National Congress of the Communist Party of China (CPC) on October15.

All the work will be carried out at night to avoid disruption to tourists visiting the square during the day and the city's traffic, said a bureau official surnamed Zhou, and is scheduled to be completed on September 25.

Chang'an Avenue, the main east-to-west artery of the national capital, and other main roads will also be lined with potted plants and flowers.
