When the episodes were broadcast in December 2017, the agency held a social media campaign encouraging Chinese viewers to translate Irish poet William Butler Yeats's epitaph (Cast a cold eye. On life, on death. Horsemen, pass by!) in order to have the chance to win a trip to Ireland.

Kenny says, the campaign has had almost 300 million total views and podcast plays.

Christopher Ledsham, chief communication officer at China Outbound Tourism Research Institute, says: "A social media marketing approach such as Tourism Ireland's successful example, is certainly one that has worked for many destinations before and can continue to be effective in the future for other destinations, if done correctly."

In addition to social media, Ireland and China have a strong shared diplomatic history to build upon.

Ledsham says, many high-ranking Chinese leaders have visited County Clare's Shannon Free Zone, which played a part in the development of China's special economic zones. President Xi Jinping visited the zone as vice-president earlier.

"Xi's 2012 visit helped put Ireland on the map for many Chinese, as he was pictured partaking in many tourism-friendly photo opportunities, including trying his hand at Ireland's native Gaelic football at Dublin's Croke Park stadium," he says.

As part of its marketing efforts, Tourism Ireland has organized numerous visits to Ireland for people working in China's tourism industry, including writers, tourism agents and travel bloggers.
