An exhibition featuring 60 works of calligraphy by United Nations officials including Ban Ki-Moon, the UN secretary general, arrived Friday in Wuhan, capital city of Hubei province, after debuting in Shanghai.

Ban's work including three characters, Qu Ze Quan, which means "bending is necessary to achieve a perfect end," an idiom taken from the ancient Chinese philosophy book Tao Te Ching.

"As a cultural carrier, calligraphy has gained great popularities among foreigners," said He Yong, head of the UN Chinese Program.

In 2009, Chinese calligraphy was enlisted by UNESCO as a representative of the intangible cultural heritage of humanity. Since 2004, many UN officials have taken part in a weekly calligraphy course organized by the UN Chinese Program.
