I received a postcard from Nguyen, Vietnam. It shows the Bonau Cave of the Halong Bay (Descending Dragon Bay). Nguyen written on the postcard that Halong Bay is a UNESCO World Heritage Site and a popular travel destination, located on the sea, east of Hanoi. The bay features thousands of lime stones.
It is a beautiful postcard and I like it. Thus, I would like to thank Nguyen for the postcard. Thanks! :)
