It's 10 minutes before your work shift begins, and you're still stuck in traffic. There's no hope of moving forward and no hope that tomorrow will be any different. For many commuters, subways are the answer to the growing headache of traffic jams in Beijing.

It begins with a trip down a long stairway. Once on the platform, doors open and everyone pushes in with force, because the opening is far too narrow to accommodate the flow. There's no time to hesitate. These trains don't wait for anyone.

It's nearly 9 a.m., but here underground, the morning rush hour has just started. Inside the box, forget about trying to get anything done. Rarely is there space to kill time. So better advice: rest your eyes. Because you still have a long way to go.

One line is finished, now it's time to transfer. You may not be stuck on the road in traffic, but riding the subway still requires time and patience!

In order to maintain crowd control, subway workers keep travelers moving in an orderly fashion. Creative and efficient and what's more it's safer.

Compared to the endless queue on the ground, the subway has its advantages. The only requirement for passengers is to have both strength and flexibility. Otherwise, you'll have to wait for the next train.

What you've seen just now is an ordinary frame taken out of every ordinary day in Beijing. On September 21st, Beijing subway's daily passenger transport volume has been rewritten with a record of 6.5 million people. Putting it in other words, the trains underground can move all residents of Madrid or Buenos Aires from one place to another, and then send them back within 18 service hours. Nevertheless, as people from all over China keep coming here, to ensure everyone is on board and arrives on time is becoming a task much harder than we could imagine.
