Last year, I traveled with my family to Ha Long Bay, which was once recognized by UNESCO as the intangible cultural heritage of mankind.Ha Long Bay in Quang Ninh province, located in the northeast of Vietnam, just 180 km east of Hanoi; It is surrounded by Bai Tu Long Bay, Lan Ha Bay, Cat Ba Island, Tuan Chau Island and Halong City.Although the area is not large about 1533 km2, Ha Long Bay owns about 1,600 limestone islands and islets. Limestone towers, large and small islands with characteristic weathered caves deep inside.I choose Ha Long Bay as the destination because every time I come here I feel relaxed in my mind, the air is clean, the people here are also very friendly. I love this place so much that I can come here again.
