Dear Tom，
I'm delighted to know you are interested in traditional Chinese festival.You must have never heard of Chong Yang Festival.It falls on the ninth day of the ninth lunar month and is viewed as Senior Citizens' Day.People often do activities like going hiking and admiring flowers on this day.
As for me, I had never thought about doing anything for the elderly until I learned about the festival at school.For the first time in my life, I washed my grandma's feet.I'll never forget the sweet smile she wore.
I sincerely invite you to come to experience Chong Yang Festival yourself.Looking forward to your coming.
Yours，
Li Hua,
