Hi Alex,
It has been a while since we meet,how are you keeping.Thanks for your letter.I am quite busy right now.I was taking care of my sick grandfather,participated in a five-day outdoor survival training and have done many more environmental protection things.It took a lot of energy and time but I like it.By the way,are you coming to visit me soon?I am looking forward to hear from you soon.
Regards,
Ming Li
