An amazing video has emerged of three men teaming up to climb a four-meter high wall in Xi'an, China.

The footage, shot on Tuesday, shows two of the men jumping on a third man's back to reach the top of the wall. The third man then takes a running jump himself and grabs onto the leg of one of the others to haul himself to the top of the wall.

According to local media the men are training to become armed police.
