Dear David,
How is everything going? My friends and I have decided to go on an adventure trip to Hainan Island during the summer holiday. I’m writing to tell you about our travel plan.
We’ll be traveling around Hainan Island from July 15 to 21. While there we will go hiking, climbing the mountains, swim near the beach and have a campfire party. We also plan to go ping if weather permits. I’d like you to join us if possible. I’m sure we will have a lot fun being together.
Please remember to pack your bathing suit and take your passport.
I’m looking forward to your reply.
Yours,
Li Ming
