The information mentioned that all of them were alone, and... they were orphans.
The local police apparently wanted to find their family members based on their identities and contact them, only to realize they were orphans. They issued a notice, hoping that people who knew these tourists would see the announcement and reach out to the police, cooperate more in the investigation to understand the tourists' purpose in coming here, their usual emotional state, etc., and rule out any suicide possibilities.
After Yu Misheng completed an inspection, it was found that out of the 16 missing people, 10 were clearly documented as orphans who came from orphanages.
Furthermore, Yu Misheng contacted other tourists who checked in on the same day as the missing ones through the innkeeper, trying to see if anyone knew these missing tourists.
Indeed, a considerable number of people knew those missing tourists after the inquiry.
