For more than 2,000 years, until they were rejected by the Maoist regime, Confucian values formed the basis of Chinese society. Rana Mitter travels from Quf u, where Confucius was born, to the centre of modern political power in Beijing, witnessing how Confucius is being rehabilitated as ancient sage, contemporary business guru and tourist attraction, and how Confucianism is being promoted as a solution to the country's 21st-century dilemmas.
