CGTN host Tianran is getting his hands wet planting coral at Wuzhizhou Island. Carefully attaching tiny coral fragments to underwater frames, he helps rebuild Hainan's vibrant marine ecosystems. This hands-on conservation effort is more than just an ecological mission; it's a growing part of sustainable tourism. Visitors can witness and even participate in restoring the ocean's beauty, making their trip a direct contribution to protecting the island's future.
