The South Korean coast guard has now managed to extract 113 bodies from the sunken South Korean ferry.
Divers have been working today to access different parts of the ship.
Koh Myung-seok is with the South Korean coast guard.
"There is a wall between the lounge and the dining hall, and it is quite difficult for us to break it down."
It's believed that close to 190 bodies are still trapped inside the ship.
However, the exact numbers are still unclear at this point, as the passanger manifests for the ferry are not precise.
Meanwhile, South Korean authorities have confirmed that two of the bodies retrieved from the ship on Monday are Chinese nationals.
A third body, also believed to be a Chinese citizen, has not yet been officially identified.
As the recovery continues, the parents of many of the teenaged passengers have issued a letter, appealing with authorities to speed up the process.
The ferry, with close to 500 people on it, capsized last Wednesday while on a trip from Incheon to Jeju Island.
The exact cause of the capsizing hasn't been made clear, though survivors say the ship made a sudden turn before beginning to list.
The capitan and a number of crew members are facing a series of charges.
