b Hi Hoa,
I'm having a birthday party next Friday at my house. Would you like to come? It'll be fun! Lots of people from my class are coming. You know some of them Dat, Quang, Hien, and Trang. Can you bring some lemonade and crisps? 
My house is behind our school, 24 Nguyen Trai Street. It's right next to the park and it's got a blue front door. If you want to join us, come to my house at 7 p.m on Friday.
Hope you can come and see me soon,

Lan
