A man in eastern China released a crab he was going to cook after it successfully untied itself.

Video filmed in the city of Jinan in Shandong Province on October 20 shows a crab using its claws to cut the rope tied around its body.

A man named Sun was heard saying to the crustacean: "If you can untie the rope, I will release you.

"Holy crap! Do I need to keep my promise to release it? He untied the rope for real! Can you survive if I released you?"

Sun then put the crab into a box and drove it to a nearby lake to release it back into the wild.

10月20日，山东济南。孙先生看着买来的螃蟹在自己解绳，随口说了一句解开就把你放生。没想到螃蟹竟然真解绑成功，孙先生也信守承诺连夜开车去附近的小湖放生。孙先生感叹，连一只螃蟹都在自我救赎，任何事情任何时候我们都要努力。
