Once the Chinese weighlifters arrive in Brazil, their temporary homes will be ready for them, as the Athletes' Village in Rio officially opens today. That means 10,500 athletes and another 7,000 staff members will start trickling into the luxurious layout. 

The 31-building compound should pamper the world's best. It's set among tennis courts, soccer fields, and seven swimming pools with mountains and the sea as a backdrop, all topped off by a massive dining-kitchen compound that's as large as three football fields.

Athletes' Village in Rio officially opens today.

Some delegations already arrived Saturday, easy to spot with banners or flags hanging off the sides of buildings. The symbols of Canada, Britain, Portugal, Finland and Sweden were among those sighted. A tiny red and yellow Chinese flag was pinned near the top of one of the compounds.

Everything about the village is massive, though fairly standard for recent Summer Olympics.

And just to be on the safe side, organizers are providing 450,000 condoms, three times more than London did four years ago. Many consider that increased supply to be due to Brazil's outbreak of the Zika Virus, which has been linked to birth defects, but organizers say it's simply about encouraging safe sex.
