The Middle-Autumn Festival is a traditional festival in China.
People do like to eat moon cakes during the day.
It is well known that moon cakes symbolize the gathering of friends and families, and are an indispensable part of the offerings made to the Earth God.
However, few people really knows the birth of moon cakes.
Today, I'd like to share some information with you.
According to a popular belief, the custom of eating moon cakes began in the late Yuan Dynasty.
At that time, people hated the rule of the Mongolians.
An insurrectionary army led by Zhu Yuanzhang planned to overthrow the rule of Yuan Dynasty.
Zhu needed to find a way of uniting the people to revolt in secret.
Zhu's advisor came up with a brilliant idea-creating moon cakes to deliver secret messages.
In this way, the insurrectionary army successfully started a uprising to drive the ruler away.
It happened at the time of full moon, which may explain why people eat moon cakes on this day.
From then on, moon cakes have become an important part of the Middle-Autumn Festival.
Traditional moon cakes are made with melted lard.
But vegetable oils are more often used today, which are better for our health.
Those moon cakes are usually put in four boxes to indicate moon's changing course.
