Political advisers in South China's Hainan province urged authorities to levy taxes on vacant homes in popular travel destinations to discourage speculation and cool the island's overheated property market.
Hainan opened a second duty-free store on Wednesday, following the success of the first, which since April has boosted domestic tourism to the province in South China.
In the 18 years since it was founded, Hainan Airlines has been doing its part to bring China to the world.
