To Department Office
Secretary Li,
I' m sorry to apply for ten day' s leave from the Aug. 23rd to Sept, 2nd instant. And I have to leave with the time is urgent. My father now in the hospital is badly ill. I have to go to see him and take care of him for a few days. You know I' m the only child in my family. Of course I will show you the telegram about my father' s illness which is received from my mother to support my application.
As concern as the missed lessons during my absence, I promise I will do my best to catch them on after I come back to the cam pus. Wish for your allowance.
Yours respectfully
