"Nearly 100 years have passed from the Qiongya revolution to the liberation of Hainan and the current construction of the Hainan Free Trade Port. But the spiritual strength has been passed down in a continuous line. This is a vivid portrayal of the original intention and mission of CPC members," Mao Zhihua said.

"In building Hainan Free Trade Port, we must always maintain the same spirit and energy — be patient, selfless and fearless to overcome difficulties —just as we had during the revolutionary war period," he said.

Experts said that, like the sea-crossing campaign 71 years ago, the construction of Hainan Free Trade Port is an unprecedented campaign that needs courage and innovative spirits to help turn Hainan into a more beautiful and prosperous island and a successful highland heralding the country's opening up.
