What does a cup of tea mean?

In the Victorian era, drinking tea was not a habit among British and Americans, so at that time, a glass of beer or a glass of wine was used to express "preference; Just to sb.' s liking; Something you like; Just to the taste. " Later, drinking tea became popular, and people even used tea instead of coffee at breakfast. Rich people will have afternoon tea. But everyone has different requirements for tea, some like China tea, some like Indian tea, some like weak tea, some like strong tea, some add sugar, some add lemon: it's really difficult to adjust. So "this is not what I like." There it is (this is not my favorite tea).

So a person's cup of tea means "like; Just to sb.' s liking; Something you like; Just to the taste "can also be written as a plate of tea.

We often hear people say that he is not my cup of tea, he is not my cup of tea. Between the lines, he is not my favorite person.
