The province continued to see a travel boom during this year's Spring Festival holiday. Haikou, its capital, witnessed 1.55 million trips during the week, up 0.45 percent year-on-year, and received 1.83 billion yuan in tourism revenue.

The province will focus on building a consumption center for tourists with global influence this year, and it will also set up a tourism management system based on international industry rules, local news site hnrb.hinews.cn said on Monday.
