Mid-Autumn Festival is one of the most important traditional festivals in China. It falls on the 15th day of the eighth lunar month, which usually falls in September or October. On this day, people gather with family and friends to enjoy mooncakes and admire the full moon.

To celebrate this special occasion, many children and adults make hand-made posters or 'handwritten newspapers' (手抄报) to display their creativity and express their thoughts on the festival. These posters are often decorated with colorful paper cutouts, drawings, calligraphy, and poems.

The content of the posters is usually related to the Mid-Autumn Festival, such as its history, legends, customs, and traditional foods. Some posters may also include information about the Chinese lunar calendar and its significance in Chinese culture.

For example, one poster may depict the famous legend of Chang'e, the Moon Goddess who lives on the moon. Another poster may showcase different types of mooncakes and their flavors. Some posters may even include DIY instructions on how to make paper lanterns or mooncakes at home.

Overall, hand-made posters add a personal touch to the celebration of Mid-Autumn Festival and showcase the beauty of Chinese culture. Through these posters, people can learn more about the festival and appreciate the importance of family, harmony, and auspiciousness in Chinese traditions.
