"I feel much better after one week's care including traditional Chinese medicine treatment," said Zhao, noting that he became more aware of the importance of looking after his health because of the coronavirus outbreak. "It's relaxing for both my body and mind being here."

Hainan has developed a portfolio of 10 major tourism products, including marine tourism, health tourism, cultural tourism and sports tourism, said Ao Liyong, deputy director of the provincial department of tourism, culture, radio, television and sports.

Eight large tourism enterprises including China Duty Free Group and China Tourism Group set up their headquarters or regional headquarters in Hainan last year.

A total of 24 tourism projects including the brands Hello Kitty and Discovery have been signed up, said Ao.

The provincial development and reform commission announced last month a bunch of key projects, among which 10 involve investment of more than 10 billion yuan each.

According to a plan unveiled in December 2018, China aims to build Hainan into an international tourism and consumption center by 2025 and a tourism and consumption destination with global influence by 2035.
