While public schools in Beijing are closed due to the red alert over smog, some private schools are still open. That doesn't mean they don't care about their students' health - on the contrary. They have shown their concern by building air-bubble stadiums with plastic domes.

They can filter the air and allow students to take part in their normal activities while pollution wreaks havoc outside. CCTV reporter visited one private school in Beijing to look inside these special stadiums.

When students in Beijing have to stay at home to avoid the choking smog, these children are happily dancing under a dome made of plastic bubbles.

This stadium has a fresh- air system that can filter polluted air and refresh it every twenty hours. The air pressure on the inside is higher than the outside, making sure dirty particles in the air can easily go out.

It's like a balloon shelter, isolating the children from the smoggy and gloomy world outside.

As shown on the phone, the reading of the average PM2.5 airborne particles in Beijing is over 300 per cubic meter, over four times the national standard. So what's the air quality in this safe haven, let's go take a look.

The air quality monitoring system shows that the PM2.5 count is 25 per cubic meter. And the kids can easily tell the differences between the two worlds.

The principal says now the stadium is not only for the smoggy days, but for everyday use.

Yi Mengde, Principal of Middle School Dept., Beijing Huijia Private School said:"We tried to move classes here if possible."

But a benefit always comes with a cost.

"The average cost of every stadium is over 5 million yuan. It's worth every single penny that we spent," said Yi.

Clearly not every child can afford the expenses here. Right now, there are three other bubble stadiums designed for volleyball, basketball and swimming. One has even been built exclusively for equestrianism, where students can learn horse-riding.

This school has created a small world for the kids to play under the dome. But it's too expensive for the general public. Let's hope that one day in the future the kids can play under the sky instead of the dome.
