Going with the flow of water and worldliness

Many people in Bulgaria's capital, Sofia, know about an ancient building on Oborishte Street - the former home of Dr Ianto Kaneti (1910-2004) and his Chinese wife, Zhang Sunfen.

The couple's lives are revealed in the documentary serial The Journey of Danube airing on Guangdong TV.

The 80-episode series features the lives of those living in the countries through which the Danube River flows, focusing on their relationships with China. It touches on these countries' culture, history, people, music, towns and cities, economy and society.
