Dear_Mike,_

The MidAutumn Day is a traditional festival with a long history which is celebrated only by Chinese people. It falls on August 15th of the Chinese lunar year, when people of a family get together and enjoy the dinner together. After that they eat mooncakes, which stands for the spirit of the festival—unity.Often, if the weather permits, they will go out of the house to enjoy the bright moonlight, talking about something pleasant. It is one of the most important festivals for Chinese people.
I wish you a pleasant journey and I'm sure you will like our traditional MidAutumn Day.
Yours,
Li Hua
