August 15th of the lunar calendar is the Mid-Autumn Festival, also known as the Reunion Festival, August Festival and Daughter's Day. Before 15, relatives and friends exchanged moon cakes. 15, married women must go back to their husband's family for a holiday. In the evening, thousands of families set up moon cakes, melons and other gifts on the courtyard, balcony and floor to worship the moon. When the bright moon rises in the east, the whole family will enjoy the moon, talk about the sky and share gifts for the moon. If someone is outside, they will leave a copy specially to show their reunion and wish them good luck.

After the founding of People's Republic of China (PRC), the Mid-Autumn Festival still follows the old custom of enjoying the moon and eating moon cakes. On this day, there are customs in Weibei area, such as steaming steamed bread, eating steamed bread, offering steamed bread to ancestors, exchanging steamed bread between adjacent doors or giving it to the elderly.

At present, it is more important to send moon cakes to each other before the festival. When buying moon cakes, we should not only pay attention to the types of colors, but also pay attention to the shape and packaging. Generally, Beijing-style moon cakes, Soviet-style moon cakes and Cantonese-style moon cakes are preferred. Or as a gift of Weinan specialty crystal cake.
