Leave of Absence
I would like to ask for leave from 28th Jan.to 14th Feb.to celebrate Spring Festival with my family.Also I have already booked air ticket in case there would be no tickets due to the coming festival.
I shall rejoin and resume work on 15th Feb.2011.（这句表明你会在假后2月15日正常上班）.
Thank you.
Yours sincerely,
