This remote Chinese school has just three students, but with live streaming technology, they share a classroom with hundreds

Thanks to high bandwidth internet technology, the classrooms at Lumacha and other schools in the northwestern part of China are no longer quiet.

Ten years ago, the grounds at Lumacha primary school in remote Dingxi, a farming village in the mountainous region of China’s Gansu province, overflowed with 300 students during class breaks. Today the schoolyard is a lot quieter: there are just three students.

The plummeting student population is a consequence of China’s urban migration, with millions of rural residents having moved to big cities over the past decade in search of higher paid jobs – most taking their kids with them.
