Tangjiu is usually made before Spring Festival, and the tangjiu made before Spring Festival is covered with plastic wrap and stored in a refrigerator to keep fresh over the year. Besides Spring Festival, the seventh day of the seventh lunar month is also a time to make tangjiu, because children under 16 years old in Shitang town will celebrate "Children's Day", and children would use tangjiu to make "manjinting" at the age of 16.
