She prepared very carefully for the four-day journey by trying to improve her heath.
H’Hen Nie said that like other members of the expedition team, she had to strictly followed regulations to protect herself.
On the first days, the team travelled from Phong Nha to En Cave where they took a rest.
On the next days, they left En Cave to Son Doong Cave. They had to face streams, slopes, cliffs which are quite dangerous.
They were really impressed by the splendid beauty of Son Doong Cave.
One of the most memorable things during the trip was she fell and collided with the rock face when climbing.
“I’m extremely happy with my experience in the largest cave in the world,” she said, encouraging people who love nature to visit the cave.
