Two black bears were spotted wrestling each other on a frozen river in northern China.

The video was filmed in the city of Jiamusi in Heilongjiang Province on March 30.

According to reports, the two black bears went into Jiaxinzi Island and disappeared in the forest after around 40 minutes.

Police officers monitored Jiaxinzi Island through surveillance cameras as well as increased the border patrol to persuade vehicles and people arriving at the area to return.

The black bear is a second-class protected animal in the country. It is rare to see two black bears together at the same time.

3月30日，黑龙江省佳木斯抚远市夹信子岛附近，沿江边境派出所民警对中俄界江黑龙江江面视频巡查时，两只黑熊出现在了监控画面中。当时，两只黑熊正在嬉戏打闹，随后沿着冰封的黑龙江江面朝抚远夹信子岛走去。
沿江边境派出所民警介绍，从视频中观察，两只黑熊体型较大，属于成年黑熊，它们距离岸边大概两公里，走走停停非常机警。大概四十分钟左右，两只黑熊进入了抚远夹信子岛，消失在密林里。由于夹信子岛距离抚远市区较近，民警通过视频监控关注该区域动态的同时，加大了对夹信子岛附近区域的边境巡逻力度，及时劝返抵边车辆和人员。
黑熊俗称黑瞎子，属于国家二级保护动物，每年三四月份结束冬眠开始出洞活动。近年来，随着生态环境改善，大型野生动物经常在抚远地区出没，但两只成年黑熊一起出现还是比较少见。（视频由黑龙江台提供）
