HE CAME IN HERE LIKE "A BULL IN A CHINA SHOP"
This expression is very interesting for Spanish speakers considering the fact that it contains one of the symbols of Spain = "the bull". This expression can be used when describing someone that is not very careful about the way they move or behave.
Example: "He came in here like a bull in a china shop and told us all to leave immediately" or "He was like a bull in a china shop, he didn't care about whether he knocked anything over".
Hope that helps!
