The discovery of Hang Son Doong
I was born into a poor family. My father died, and my family had no rice fields, so I had to go to the jungle for work to support my family. Over a period of 13 years, I learnt the location of many caves in the areas I passed through.
In the rainy season of 1991, I went with two others to look for the aloe wood, which is very precious and exists deep in the jungle. It is very hard to find. We separated and I went through Hang En. The next day was raining very hard, so I looked for somewhere to stay for the night. Fortunately I found the entrance of an unknown cave. After the trip I returned home, and gradually forgot about this cave.
In 2006 I met the British Caving Expedition and took them to the Doong area, where they explored many caves. In 2007 I took them to the Doong area again for further cave exploration. On this trip we found Ho Nui Cave. Before the end of the trip I talked with Mr. Howard. Although we can’t speak the same language I knew that he was looking for a cave to connect Hang En, with another cave Hang Thoong, in the Tra Anh area.
I had a memory of a cave in this area, which maybe had a wind, and fog blowing from the entrance, but I couldn’t remember the location. I went off for an extra day searching for this cave, but unfortunately failed.
I didn’t want to give in. Because of my great admiration for the explorers’ abilities and their friendship, I wanted to show them this cave. In January 2008, I spent my own time and money to return to the Doong area to look for the entrance. Relying on my memory and experience, I followed the stream from Hang En, and fortunately found the big cave entrance in about half a day. I cut down some wild saplings to reach the entrance. Finally using my knowledge of the jungle, I found the best path to take the cavers to the entrance, and made it as easy as possible. It was now 2pm on the third day, so I returned to Phong Nha and waited for the expedition to return.
In March 2009 the expedition returned to Son Trach. On the first trip I really wanted to take Mr. Howard to the new cave, but another team came. At that time I was worried in case the cave was dry and not very long. But thank god, in this trip the cave length was measured at about 5k, and there was a large subterranean river. The explorers realized that this could be the largest cave passage in the world.
I believe that I have made them all especially Mr. Howard very pleased, because this is an important cave which connects the Doong area with the Tra Anh area.
