Beijing's ambition to open more parks free of charge to the public has simply added more venues for some visitors to display their uncouth behavior.

Last month, more than ten parks were added to the free parks list, bringing the number of free parks to 123.

The Beijing government has launched a campaign to promote civility among Chinese travelers as a response to negative publicity garnered by Chinese tourists' behavior overseas. The campaign will last until after the Olympic Games.

Carving names, spitting, talking loudly and random littering are common scenes in Beijing parks.

The official campaign was based on guidelines drafted by "expert groups" and Party and governmental departments.

Civil servants and state company executives will be specifically targeted for training, while the general public will be educated via the mass media and through pamphlets distributed at public transport stations, hotels, travel agencies, tourist spots, schools and work places.

In addition to 250,000 foreign tourists, China expects that over two million domestic tourists will visit Beijing during the Games.
