BEIJING — In honor of the upcoming 18th Party Congress of the Chinese Communist Party, here are just a few of the things you cannot do in Beijing.
Watch foreign television while you exercise in a health club. Attend an outdoor concert. Do your homework online. Buy a knife in the supermarket. Buy lunch from a food cart. Run a marathon. Bring balloons.
Mao Zedong once said revolution is not a dinner party, but the party congress scheduled to begin Thursday — during which a new Chinese leadership will be anointed — isn't looking like much fun, either.
Since September, in the name of security, Chinese authorities have turned to various baffling regulations that are snuffing much of the life out of Beijing — a city of 20 million — and police have increased their presence to keep the capital's streets free of problems. As a result, many residents are finding the country's political event of the decade to be nothing more than a colossal inconvenience.
Countless public events — cultural, sporting and business — have been canceled or postponed with no explanation and scant notice.
The Beijing Marathon, a world-class event normally run in October, was postponed to an undetermined date. Attendees at a legal conference scheduled for Oct. 10 arrived to find the doors taped shut and a notice saying the building had been closed by the fire department.
It has become difficult to find street vendors selling jianbing, a Beijing-style fried pancake that used to be as ubiquitous as hot dogs in New York, or someone grilling chuan, the Chinese version of shish kebab.
At the city's five-star hotels, guests pounding away on the running machines and cross trainers can't do so to the patter of CNN or a number of other programs: The television sets are all fixed to state-run channels.
"You can't see foreign programs anymore because we are not allowed to play them. I don't know why, but the relevant parties said it was not allowed," said an employee in the gym at the Grand Hyatt.
At the Bookworm, a popular English-language bookstore, the section previously devoted to Chinese politics and history has been stuffed with Stephen King thrillers, child-rearing guides and Victoria Beckham's "That Extra Half an Inch."
"We're just reorganizing," one employee said. "They'll be back after the party congress."
The congress is the whopper political event in China, sort of like the U.S. Republican and Democratic conventions and Election Night rolled into one. Though the event takes place every five years, this year's gathering is especially important because both President Hu Jintao and Premier Wen Jiabao are to be replaced, along with other members of the top leadership.
Thousands of party cadres will be in Beijing for the occasion, making heightened security understandable to some extent. Still, it can feel like overkill.
Though the weeklong congress will be held at the Great Hall of the People, the security cordon extends far beyond Tiananmen Square.
Across town in Sanlitun, a restaurateur was visited recently by 20 municipal inspectors whose leader told him: "Avoid trouble and close your doors until it's over."
All facets of Chinese society have been affected. The China Securities Regulatory Commission warned stock traders to keep market volatility to a minimum and not "buck Beijing" ahead of the political event.
And some of the predominantly male delegates arriving from around China may be particularly disappointed by how far officials have gone to eliminate distractions from the endless speeches and dinners taking place behind closed doors. At least half the capital's prostitutes have been arrested or driven out of town, according to Li Dan, whose nonprofit group provides outreach to sex workers.
Train stations throughout the country have barred anyone who is not a passenger from platforms. A family in Shenzhen, more than 1,000 miles from Beijing, complained about not being allowed to help a 90-year-old relative with his luggage.
The websites of China's international schools, which students use for online homework assignments, have seen unexplained disruptions.
The inconveniences are large and small: Yang Rui, a nationalist television host sometimes dubbed the Rush Limbaugh of China, complained on his blog about a recent experience in a supermarket.
"I looked everywhere for a fruit knife, but I failed. So I asked the clerk. He said, 'All knives are off the shelf before the 18th party congress.' "
The precautions, if intended to avoid scandal, feel somewhat like locking the barn door after the horse has escaped. The country has already seen a fair amount of unwanted attention during the last year or more.
In recent months, for example, the wife of a then-Politburo member, Bo Xilai, was convicted of murder, and a top security official, Wang Lijun, sought asylum in a U.S. Consulate. Hu Jintao's top aide had to step down after his son crashed his Ferrari, with two naked women as his passengers. The presumptive next president, Xi Jinping, disappeared for 17 days, a vanishing act that remains unexplained.
The congress's inconveniences were drawn out this year because of secrecy over the date. By the time it was announced in September, lower-level government officials who had been left in the dark had already decided it was wisest for them to clear the calendar for much of autumn.
"We still have an underground party which is scared to reveal its real moves to the people, even the dates of its meetings," dissident artist Ai Weiwei said in an interview last month.
Li Dan, who runs the Dongjen Center for Human Rights Education, said authorities were using the congress to maintain their grip on the people.
"It has become a habit over the years. At the lower levels, officials are afraid they will be punished if anything goes wrong at a crucial moment," Li said. "There is always, every year, some big reason they claim they cannot be relaxed."
China has been lurching from one sensitive moment to the next — the 2008 Olympics, followed in 2009 by the 60th anniversary of the country's founding and last year's 90th anniversary celebration of the Communist Party — each being an occasion to round up malcontents and cancel public events.
Event planners try to tiptoe around the land mines in the calendar, anticipating what might be a sensitive time.
Promoters of the Dreamer Festival, which features indie rock 'n' roll musicians, this year moved the outdoor concert from Beijing to Tianjin, 70 miles away. But it was stopped anyway, forcing organizers to cancel contracts with artists, airlines and hotels and refund tickets.
"We dreamers were too naive. We thought we wouldn't be affected by XX," one of the festival organizers wrote on a music blog, using "XX" instead of writing "18th congress."
That's another taboo. The term "shi ba da" (meaning 18th congress) is among those banned from the Internet in China.
