46．"May we all be blessed with longevity （長壽，長久） .Though miles apart，we are still able to share the beauty of moon together" wrote Su Shi，a poet （詩人） during the Song Dynasty，in his well-known poem to his younger brother Su Zhe.
The moon is at its brightest on the 15th day of the eighth month of the lunar calendar （陰歷） .On this day，people celebrate Mid-Autumn Festival.It has been enjoying great popularity all over the country.
In ancient China，that day was a harvest（收獲） festival because crops （莊稼）were harvested during that period.It was a time for relaxation and celebration.
Just like Thanksgiving in Western countries，families also try to get together for the Mid-Autumn Festival in China.Usually，no matter how far away or how busy they are，people will try to return home for the celebration.
The Mid-Autumn has its own special food just as other traditional Chinese holidays.People eat moon cakes with fillings such as sugar and eggs.The round shape of the cake makes it look like the full moon.The full moon and moon cakes stand for family reunion （團(tuán)聚）.
With the beautiful moon up in the sky，people sit together，enjoy the full moon，eat moon cakes and fruit，share the stories and express the best wishes for the family members and friends who live far away.
