What is the miscellaneous grain beam used to clean the house?

In Huangdi Neijing, the five grains are considered as "japonica rice, adzuki bean, wheat, soybean and millet", while in Mencius Teng Wengong, the five grains are called "rice, millet, millet, wheat and glutinous rice" and in Buddhist sacrifices, they are also called "barley, wheat, rice, adzuki bean and flax". At present, the general "whole grains" refer to rice, wheat, sorghum, soybeans and corn, while grains other than rice and flour are customarily called whole grains, so whole grains also refer to food crops.
