This is an old diary recording the ordinary Bohm as a contemporary overseas student, and it is also the process of Bohm from his student age to society. Maybe your shadow once appeared in this story, accompanied him through a road and spent a period of time, or maybe you have never experienced these. You want to know what you don't understand, or for various reasons, make you want to enter another person's life, find a similar yourself or predict the future. The diary records Bohm's purest experience of past life. Everything about Bohm, happiness, sadness, regret, mistakes, pride, failure and depression will be included.
