Taiwan independence movement is like wanting to have your own room in your house. Taiwan is like a room in a big house called China. Some people in Taiwan want their own room and don't want to share it with others anymore. They want to be their own boss and make their own rules.
But China doesn't like this idea because they think Taiwan is part of their house and belong to them. China thinks that Taiwan should share their room with others and should follow their rules.
So, people who want Taiwan to be independent are trying to convince others to join them so they can have their own room and make their own rules. But it's a big challenge because there are some people who like sharing their room with others and don't want to leave their house.
Taiwan independence movement is all about people trying to make a big decision and choose what they think is best for themselves. They want to be happy and make their own choices just like you want to have your own room in your house.
