Dear All,
I am writing on behalf of our Student’s Association to send our warm welcome to all of you. And in order to make you adjust to life in China, I am making some constructive suggestions with regard to the life in our university.
To begin with, you’d better familiarize yourself with the campus facilities as soon as possible. The library is a great place to start, as it is equipped with a wide range of books and resources. Secondly, joining some clubs or organizations can be a good way to meet new friends and expand your social circle. Don’t forget to try out the local food! It’s a great way to experience the culture.
We hope these suggestions will be helpful to you. Please feel free to ask us anything if you have any questions or need further assistance.
We look forward to your arrival and wish you a pleasant stay at our university.
Sincerely,
Li Ming
[学生会名称]
