Dear Angel Lee:
How are you doing?Hope you are fine.
Chinese annual traditional festival"Mid-Autumn Day" is comming.During this festival ,we always spend having moon-cake and appreciating the big and round moon hung in the sky in the evening together with the whole family.It means that the family is completely every year and the relation is very good .
It's said that the moon during that nigh is biggest and roundest of the pass 9 years.It sounds so wonderful and we are expecting.We would like to invite you to share that special day.Eating delicious moon-cake with nuts,agges,looking at the beatiful moon in the sky,chating and cheering,it's must be very interesting.I think you must enjoy that night!
Looking forward to your soonest reply.
