Spectators planning to attend the Beijing Olympics next month have been warned to avoid nudity, swearing and drunkenness.
Issuing the "Spectators House Rules" along with a campaign billed as "Good Habit for a Good Games" , the Beijing Olympics committee set out how they expect those attending the event to conduct themselves to prevent causing embarrassement for their hosts.
Large banners and flags are banned, with a view to preventing the political protests the authorities fear, while vices such as gambling along with streaking are also prohibited.
The eclectic rules include a warning that while fountain pens, suntan lotion and lip gloss are permitted, they must only be brought along in small quantities.
Babies have also fallen foul of the committee, which is discouraging parents from bringing them to the event.
Meanwhile, the once familiar cry of peddlers selling pirate DVDs on the streets of the Chinese capital is disappearing as the government finally acts on pledges to end the practice – at least until after the Olympics.
The authorities have ordered a "100-day drive against pirate copies", with officials on call 24 hours to act on reports of illegal CDs and DVDs going on sale.
"Strike hard against all kinds of pirate copies violating rights and against illegal publishing activities," their notice said. "Go all out to create a healthy cultural market environment for the Beijing Olympic Games."
They have already begun to act in recent months, closing down some shops that specialised in selling what were often poor quality versions of international blockbusters, usually within two or three days of their going on general release.
The Chinese government has dismissed an allegation by Amnesty International as groundless after the human rights group alleged that that dissidents were being rounded up ahead of the Games.
