Why do some Mexican guitar music sound like flamenco? Is there any origin between the two?

Flamengo is a comprehensive art in Spain, which combines dance, singing and instrumental music.

Before the rise of Britain, Spain was a very powerful colonial country in the world, and Mexico was a colony of Spain for a long time, which affected its economy, language and culture. Now the official language of Mexico is still Spanish.

So * * * has many similarities, at least very similar.

As for the historical origin of the two countries, it is very long. You can find it by reading history books or searching online.
