Hi [家人的名字],
I hope this email finds you well. I just wanted to let you know that I'm doing great here in [留学国家] and that I'm really enjoying my studies. The cultural experience has been enlightening and I'm learning so much.
I miss you all and can't wait to catch up on everything when I get back. In fact, I've been thinking about our family gathering coming up. I would love to be there to celebrate grandma's 80th birthday with everyone. Please let me know if there's a date and time that would work for you, and I'll make sure to be there.
Thank you for your support and love. I'll write again soon.
Take care,
[您的名字]
