I feel so happy to receive your letter.This time,I want to introduce one of the traditional festival in China--Dragon Boat Festival to you,and I hope you will like it.The Dragon Boat Festival,also called the Duanwu Festival,is celebrated on the fifth day of the fifth month according to the Chinese calendar.For thousands of years,the festival has been marked by eating zong zi (glutinous rice（糯米）wrapped to form a pyramid using bamboo or reed leaves) and racing dragon boats.The festival is also well known for its dragon-boat races.
I like Dragon Boat Festival very much as it is very interesting.I can hardly wait to eat Zong Zi and watch dragon boat race on that day.
Yours,
Tim
