In a country where provincial capitals are rarely known for their beauty, Nanjing shines. The construction work that's churning up the face of China seems to have affected this city less than most and it remains a place of broad boulevards and shady trees. This is just as well considering the oppressive summer heat that grips Nanjing, which is known as one of China's 'three furnaces'. The city enjoyed its golden years under the Ming, and there are numerous reminders of the period to be found. One of the most impressive is the Ming city wall measuring over 33km - the longest city wall ever built in the world. About two-thirds of it still stands. On the slopes just east of Nanjing is the Sun Yatsen Mausoleum. Sun is recognised by the communists and the Kuomintang alike as the father of China. Nanjing is asscessible by rail, bus and air. It is roughly 1000km (620mi) from Beijing.
