Green dream dawns for a rainforest lost and regained

At the foot of Niuling Mountain in the southeast of Hainan island, lies a mysterious valley that is a palace of plants - from lowly weeds to the nobility of flowers.

Named Xinglong Tropical Garden, located a little bit north of the northern altitude of 18 degrees, the garden is home to more than 1 million trees belonging to 4,500 tropical species.

Famed as a natural oxygen bar, it boasts more than 65 kinds of rare plants that are on the endangered list, such as Shorea roxb, Hainan palm, Dracaena cochinchinensis, Vatica astrotricha, and Dalbergia odorifera, all collected from other places, both in China and overseas.
