Outward Bound Training

    Outward bound refers to the result of team training in some form, usually through the natural environment such as mountains and rivers, and through meticulous design activities to achieve the purpose of "tempering willpower, cultivating sentiment, perfecting personality and melting team".
    Expanding training not only enables individuals to get exercise in skills and psychology, but also enables participants to deeply appreciate the importance of teamwork and greatly enhance team cohesion.
