Workers are stepping up the construction of the two lighthouses on Meiji and Yongshu reefs.

They were designed to provide navigation services such as positioning reference and navigation safety information to ships in the vicinity.

The lighthouse on Meiji Reef is over 60 meters high and is the tallest of all the structures on the Nansha Islands.

It has a range of over 20 nautical miles.

Meanwhile, a modern hospital will also be completed on Yongshu Reef later this month.

In April, China finished the construction of a lighthouse on Zhubi Reef, also in the South China Sea area.
