Sitting on a hilltop overlooking the new town of Muang Yawn is a two-storey house that is slowly becoming a tourist attraction for foreign visitors allowed to enter the area, which had until recently been declared off limits to outsiders.
Until two years ago this was the home of Wei Sai-tang, a young Wa military leader currently serving a 50-year prison sentence at Panghsang -- the headquarters of the United Wa State Army (UWSA), which he belonged to.
It looks like any ordinary house, apart from the fact it has a tunnel linking the basement to a small exit on the hillside.
According to the guide, the owner's first wife sleeps in the basement and his four mistresses sleep on the second floor, each with their own room.
His replacement, Ai Pang said Sai-tang had been accused of producing methamphetamine tablets, and counterfeit Thai and Burmese money.
"It was very difficult taking Sai-tang down," Ai Pang said. "He ran a very secretive operation with heavily armed guards around him."
Ai Pang went on to explain how UWSA officials had tricked Sai-tang into leaving his stronghold and lured him on to a flight before they could arrest him and charge him with the crimes.
UWSA officials reportedly found huge sacks filled with methamphetamines in the basement along with the counterfeit notes, he said.
The house was opened to a group of 20 Thai journalists invited to the UWSA-controlled area for a three-day visit. The visit to Sai-tang's house took place one day before the opening of a Thai-funded hospital, which supplements a Thai-Burma crop substitution project.
What is ironic about this project, as well as Ai Pang's statements, is that the US State Department considers the UWSA to be world's largest armed drug-trafficking group.
Moreover, Prime Minister Thaksin Shinawatra, who had cancelled his visit to Muang Yawn for the opening ceremony, has even threatened to send troops to rout the UWSA if they do not stop flooding the country with methamphetamines.
The event on Friday brought scores of Thai officials, headed by Third Army commander Lt-General Picharnmate Muangmanee, and marked a major turn around in Thailand's approach to the UWSA.
This perhaps explains why UWSA chairman Bao Yu-xiang did not hesitate to show up at the hospital opening ceremony.
The photograph of Bao smiling and holding hands with the head of the Burmese Army's Triangle Command, Khin Zaw and Lt-General Picharnmate was meant to show the world that an old chapter filled with bloodshed and cross-border clashes between Thai and Wa soldiers was a thing of the past.
Bao also asked for more cooperation from Thailand in all areas, including development and crop substitution, as well as for technical advisers.
