Zhongshan Hall is a building in Taiwan that is really important to the people who live there. It's like a giant house where important things happen, and people go there to do important work or watch performances.
The building is really old and has been around for a very long time, since even before your mommy and daddy were born! It was built in 1928, which is when some of your great-grandparents might have been babies.
Inside the hall, there is a stage where people can perform plays, music, and dance shows. The stage is where people can see their favorite stars and watch amazing things happen. There are also lots of seats for people to sit on and watch the show.
Sometimes, people use the hall for really important meetings as well. Just like how in school, you have meetings with your teachers and principal to talk about important things, grown-ups also have meetings too. They talk about things like how to make the city better, or how to help the people who live there.
So, Zhongshan Hall is like a really big, fancy house that people in Taiwan use for important things. There are shows and meetings that happen there, and it is a very special place for the people who live in Taiwan.
