sticky food. The sticky bean bag is a kind of sticky food that the northeast people like to eat during the Spring Festival. It originated from the "yellow steaming" in Changzhi, Shanxi Province, and was brought to the northeast by Shanxi immigrants who ventured to the East. Its advantages are strong satiety and easy to resist the cold weather in the northeast, so it became a sticky bean bag in the northeast, which was made by yellow wheat and adzuki bean stuffing.
