There is a story about the source of inflation. During World War II, many British ships sank in the Atlantic Ocean due to the attack of German submarines, and a large number of crew members fell into the water. Due to the cold sea and being far away from the mainland, most of the crew were killed, but few people survived after a long ordeal. When people learn about these survivors, they find a very surprising fact, that is, these survivors are not all strong boys as people think, but most of them are old and weak. After a period of investigation and study, experts finally found the answer to this question: the key to these people's survival lies in their good psychological quality, strong desire for survival and good sense of teamwork. When they encounter disaster, their first thought is: I must live for my family. And those young sailors may think more: this is over, we are so far from the shore, the sea is cold, and there are sharks, so I can't go back alive.

At that time, Kurt Hann, a German, suggested that some natural conditions and artificial facilities should be used to make young seafarers do some psychologically challenging activities and projects to train and improve their psychological quality. Later, his good friend Lawrence set up an Adebayor Weihai Training School at 1942, which was the earliest prototype of outward bound training for young seafarers.

After the war, this novel training mode was retained. After years of improvement and development, it has become our current outward bound training. At present, outward bound training is mainly used in enterprises and teams to help employees and team members improve their personal qualities and build team cohesion.
