In Halloween,there are many activities.I like playing Trick or Treating most.In Hong Kong,although we can't visit other people 's house,ring the doorbell and shout'Trick or
treat',we can ask our friends 'trick or treat'in Halloween and if they don't give you a treat
you can play trick on them.Usually people will give us some sweets or snacks.It's so fabulous that we can play tricks on people and get some treats without using money to buy during this activity.
