BEIJING  Domesticated pigeons of this city, take note: Until Oct. 1, you are prohibited by government edict from flying over the center of China’s capital.

Do not take it personally, however. The government is preparing to observe the 60th anniversary of the People’s Republic of China with a parade that will make 76 trombones look like a child’s plastic kazoo. And nothing  not unauthorized window-peeping, nor marchers’ mental health, nor even the chance that pigeons might muck up displays of aerial might  is being left to chance.

China’s government at times resembles an exasperated parent trying to rein in a pack of rebellious children. Its edicts are persistently flouted by censor-dodging Internet users, wayward local officials and rioting Uighurs.

But when it comes to the impending National Day celebration in Beijing, the government appears fully in control. When swarms of soldiers, throngs of tanks and flocks of floats roll past Tiananmen Square on Thursday, 10,000 police officers and security guards will monitor Beijing street corners and checkpoints for evidence of potential party-spoilers. As many as 800,000 volunteers have also been enlisted to help maintain security.
