Jimmy Lai owns a newspaper. He is a famous man. A judge says he is guilty.
He did things that were not allowed. He worked with other countries. This is a big problem. It is bad for newspapers.
Mr. Lai is 78 years old. He had a newspaper called Apple Daily. It is not open now. He might go to prison.
A judge made this decision. She said he used his paper. He wanted other countries to help. He met with leaders from the US.
Many countries are not happy. They think it is political. They say he is punished for talking.
This is a big decision. It shows China's power. It shows problems in Hong Kong. It shows a fight for freedom.
