Introduction to the alkali boiling pot: The cauldron in the museum was built in the late Qing Dynasty. It was first used as a ritual tool in the Heidi Temple and was used to cook porridge and give alms to the poor. Later, it was brought to Qian'an County along with the alkali cooking on the grassland. During the period of the People's Commune, it was used to make alkali, horse feed, soy milk, and stewed pork vermicelli, a famous Northeastern dish. After the land was contracted to each household, it was distributed to individuals, and it was also used as a bathtub. The experience of Daguo is a reflection of the century-old history of Dabusu and is a product of the changes of the times.
