In 2004, I read a book called “Across China On Foot”, written in 1910 by an Englishman named Edwin Dingle. He walked from Chungking southwest through Sichuan and Yunnan to the Burmese border.

Each time I walk, I start from exactly the place I last stopped. So it is not contiuous as was Mr Dingle’s. So in one way, it is simply a series of Sunday strolls….
