It is a little too much even if it is a letter to the exchange student.
I will skip some of the details of too much complexity and highlight only the key points. I hope the below serves you.
Dear Chan,
I am writing you to express my warmest welcome of your coming to live with us and study at the University of Hong Kong (HKU).
I am a kindergarten teacher working in Kowloon. And I am attending cources on pre-school education 2-3 evenings per week. So you may find me quite occupied during the week. However, my job has more time-offs like school holidays, in which we may spend time touring around as you will also having time off from your school, too.
I live with my parents and two brothers in a private estate named XXX in Shatin. We are all Christians. My two brothers also attend HKU in Year 3 and Year 1, I am sure they can take care of your needs on campus. My dad is an accounting clerk and my mom is a homemaker who takes care of all of the domestic needs and feeds us well. I have made the arrangement for you to share a bed room with me.
I hope these brief introduction will give you some sense of the living condition and atmosphere of my family. Once again I welcome your stay with us in the coming X years (?). When you have the date and time of arrival, please notify me early so that we may arrange to pick you up at the airport.
