Members of the Wild Boars soccer team, ranging in age from 11 to 16, entered the cave with their coach during dry weather.
Luis Urzua, a former Chilean miner who got stuck for 69 days inside a gold mine, said the boys should be cautious with financial offers and stay close to their families.
"The area will become a living museum to show how the operation unfolded", former governor Narongsak Osottanakorn, who led the risky rescue mission, told a news conference.
"We didn't want the children to walk because it is really tiring from Chamber Three to the cave mouth", Apakorn said.
The boys had earlier received an invitation to come watch the World Cup final in Russian Federation, but doctors said they could not go as they were still confined to their hospital beds. And then the miracle: they got out.
With the boys still recuperating in hospital, US-based production companies have already taken an interest in turning their story into a motion picture.
But he had denied they were knocked out for an operation the chief of the rescue had dubbed "mission impossible".
Nine days later British divers found the disheveled and hungry group perched on a ledge 4 kilometers (2.5 miles) inside the cave.
At a school opposite the hospital in Chiang Rai where the boys are recovering, schoolchildren were in an excited, celebratory mood.
Getting them out - which involved teaching boys as young as 11 who were not strong swimmers to dive through narrow, submerged passages - proved a monumental challenge.
The extensive search-and-rescue operation, which included more than 1,000 people from various nations, has now switched to a treatment process. "This mission was successful because of cooperation from everyone", he said. The navy has a motto: 'We don't abandon the people'. I think it was the result of an worldwide team of military and civilian divers working alongside the Thai Navy.
"Hooyah! Mission accomplished", read one headline, echoing the rallying cry of the SEAL unit.
Foreign helpers, including some of the world's best cave divers, also began their journeys home.
The fate of the boys has even resonated as far as Russian Federation, where soccer's World Cup is reaching its final stages. Thongchai said no one is blaming the coach, the last to be evacuated from the cave, for his decision to take the boys inside for a hike after soccer practice.
Like the Chilean rescue, the Thai drama showcases real-life courage in the face of harrowing circumstances, said Mike Medavoy, the Oscar-nominated producer of "The 33".
The saga is reminiscent of the 2010 rescue of 33 Chilean miners who were trapped for 69 days, a tale that was turned into the 2015 movie "The 33" starring Antonio Banderas.
