This is the story of Christoph Rehage. A German who left home well shaved and decided to take a flight to Beijing to walk home.
He did not fully fulfill his purpose although he did cover the 4,646 kilometers that separate Beijing from Ürümqi to the northwest of the country, in the border with Mongolia.
The video is well edited and through its images you can see the tremendous change of look that Chris experiences from the day of departure until the time to return home.
A tremendous experience. His website is called The Longest Way although I have been wanting to see his adventures since it is temporarily not working.
