AWAY from the hustle and bustle of China’s major cities, one of the most beautiful areas one can visit is Yan’an, sacred land in China’s revolutionary history. That’s what I decided to do on the 105th anniversary of the party’s founding this week.Just one hour away from Xi’an thanks to the country’s legendary high-speed rail, this is where the Long March concluded in 1936 and the Communist Party established its headquarters for the coming battles of what would become the most decisive years of war and revolution.
