My grandma is Manchu and she doesn’t eat beef. I would like to know if this is the case?

Gui Fang may be one of the ancestors of the Manchu people. He may even be an immigrant from the Sanxingdui civilization. The Manchu people are descendants of the Yellow Emperor and retain the custom of raising pigs and dragon culture. They live in the location of the Hongshan Culture and its Surrounding areas. When people have religious beliefs, their diet is also influenced by this religious concept.

Therefore, the Manchu people in my country have the custom of not eating beef
