1, Shandong people like to eat green onions, which is related to history, customs and eating habits. It's called summer onion, also called shallot, and it's native to the Central Plains. Legend has it that Shennong discovered it when he tasted a hundred herbs. The green onions we are talking about now are actually winter onions, also called shallots, which were introduced from Shanrong, Shandong Province.

2. So where is Sun Rong? Some people take it for granted that Shanrong is located in the west of China, adjacent to Central Asia, according to the saying of "Dongyi, Xirong, Nanman and Beidi". Actually, this is not right. Shanrong, also known as Beirong, was a powerful minority in the north during the Spring and Autumn Period and a branch of Xiongnu. In today's northern Hebei Province, southwestern Liaoning Province and southeastern Inner Mongolia, countries such as Solitary Bamboo, Ganoderma lucidum, Tuhe River and Endless have been established.
