Letter(Today's English National College Entrance Examination）（我的高考第一篇应用文写作15分）

Dear Ha...什么的（我忘了），
I'm writing to intive you to stay at my home during Spring Festival, which is scheduled to start on lunar January 1st.
There will be some family members at home, my parents, two cousins and my sister included. I am firmly convinced that you will be more than happy during this festival. Not only can we watch annual TV shows, but also enjoy eating delicious food. So exicted am I that I can't wait to have this festival with you.
Looking forward to your reply!
yours sincerely,
Li Hua

There's not much to correct here, so congratulations on your English skills! We may word things differently, such as "You're invited to stay..." instead of telling that you're writing. The recipient knows that you are writing, so it's not necessary to state that you're writing. However, your version is fine. I've corrected a couple sentences as follows: "Not only can we watch annual TV shows, but we can also enjoy eating delicious food. I'm so excited that I can't wait to enjoy this festival with you." Repeating 'we' sounds better, and without it, it sounds awkward. Your word order for the first part of the other sentence is very awkward, and the use of "have" is not quite correct. When you sign off, you'll want to capitalize "Yours." Here is a link to show line spacing for both the greeting and salutation. https://www.wikihow.com/Write-a-Friendly-Letter I hope you find it helpful.
