Okay kiddo, let's talk about The Pusan Newport International Terminal (PNIT)!
PNIT is a special place where big boats called ships from all over the world come to visit. It's located in a city called Busan, which is in a country called South Korea.
Now, when these ships come to PNIT, they need to be able to park somewhere so that people can take things they brought with them off the ship, and put things they want to take with them onto the ship. It's kind of like when you park your stroller at the mall before going shopping.
PNIT has a really big parking lot, and it's actually one of the biggest places in the world for these big ships to park. It's so big that it can fit more than 20 ships at the same time!
But just like with your stroller at the mall, the people who take the things off and put the things on the ships need to make sure everything is in the right place. They even use big machines called cranes to help them pick up and move the things back and forth.
So, in short, PNIT is a place in Busan, South Korea where really big ships come to park and exchange things. And it's so big that it can fit lots of these big ships all at once!
