How does a Scrum Master apply scrum to life?

Hello everyone. It's been a year before I write.

Recently, I read a lot of articles about Scrum in sharedocumentfree but it is painful that every article if not translated from Scrum Guide is also an excerpt of the Scrum curriculum of the most prestigious Scrum /Agile training party in Vietnam today. The content of these two is almost the same theory, so I have the feeling that there is only theory here, but it is unlikely that everyone has understood and practiced correctly (but in fact with occupational diseases or having to borrow code here and there, the possibility of cherry-pick Scrum error is extremely common). So I'm going to write this to share with you.
