One possible version:

Dear friends,

     When we receive pocket money from our parents, how will you do? Now I will give you some advice.

You can put the money into the bank, it's a safe and convenient place for the money. We should form the

habit of saving money. We also can buy books, which we are longing to buy. We can get knowledge from

the books. And also we can use the money to raise our interest on music, PE or stamp collection. All in all,

we should not waste the money because earning money is not easy for our parents. We should form the

good habit of saving money when we are young.

      Thank you!
