Jimmy Lai's mitigation hearing begins in Hong Kong

Jimmy Lai, a well-known businessman and critic of the Chinese government, is having a hearing to decide his punishment.

He was found guilty of working with foreign countries against China and publishing things that the government didn't like.

This trial is very important because it's the first time someone so well-known has been charged under new security laws in Hong Kong.

Many countries and groups around the world are worried about this trial and think it's not fair.

The Chinese government says the trial is fair and that the new laws have made Hong Kong safer.

Lai has been in jail for a long time and his family is worried about his health.

The hearing will last a few days, and then the judges will decide his punishment later.
