    It's still the holiday season and students in the UK are enjoying their winter break (休假).
    Tiffany in Guangdong asks us about how British students spend their winter break.
    For some, it's a time to study because they have exams next term. Some might have to study. They have to read some books. They use the winter break to catch up with(赶上) their reading. But some students can Let their hair down and celebrate Christmas and New Year with a few drinks.
    This holiday is also an important time to chat with the family and maybe get some sleep too. Some lucky students are going away on holiday but it won't be long.
