Dear Zhang Ming，
As my birthday will take place on next Saturday， my parents have insisted on having a birthday party for me。 They are very anxious to meet all my young friends， and they want me to have a good time on this occasion。
The party will begin at 7 o"clock this Saturday evening。Please come early。 You can take a No。 15 bus and get off at Xinjiang Road。 Go straight ahead and walk across Wulian Street。 The restaurant is on the corner of the street。 Its name is Da Fang Restaurant。 We are looking forward to seeing you then。
With best wishes!
Yours sincerely，
XXX
