Heroic firefighters freed three children from a narrow gap in between walls after they got stuck inside when playing hide and seek in eastern China.

The video, filmed in the city of Ningbo in Zhejiang Province on April 6, shows firemen using a hydraulic spreader to expand the one-metre-wide wall gap and tearing down the bricks.

After fifteen minutes, a seven-year-old was rescued first, followed by a five-year-old boy and a seven-year-old boy.

According to reports, the children were playing hide and seek and walked into the narrow gap between the two walls. However, they realised they were trapped inside when they attempted to walk out.

Fortunately, no one was injured. The video was provided by local fire brigade.

4月6日12时47分，慈溪消防救援大队指挥中心接到市民报警称：位于宁波慈溪市崇寿镇老湾村有3名小孩被卡在墙内。接警后，大队立即调派两辆抢险救援消防车及15名指战员赶赴现场进行处置。
3名幼童：一个7岁半女孩，一个7岁男孩，一个5岁男孩。由于在玩捉迷藏想到躲在墙缝中，当走到尽头时发现墙缝变窄，想原路返回也不行，最终全部卡墙缝里，导致身体无法动弹。
侦查发现小孩卡在墙角内侧一米处，由于中间间隙过小，小孩身体无法取出，使用绳索也无法拉出，指挥员了解现场情况后立即制定救援方案，决定在做好被困小孩的安全防护工作后，拆墙施救！为确保在拆墙时墙壁不发生倒塌，决定先用顶杆在墙壁的上段固定住，然后从墙壁三分之一处利用液压扩张器把包裹墙壁的水泥清除掉，随后利用撬杠将墙内砖块一个一个拿出来，扩大救援空间。
经过救援组近10分钟的紧张工作，在最外侧的女孩成功救出，随后中间五岁的男孩也顺势而出。
当准备救助第三个男孩时救援问题也随之而来，由于男孩被卡位置深且体型较大，无法动弹，特别是头部位置稍微动弹就被墙壁刮擦。
考虑到这一点消防救援人员决定在把破拆深度提高，5分钟后，最后一名幼童被成功救出。
所幸三名幼童都无大碍。整个救援过程经过了十五分钟。
