Maybe rare tea set from Mao ZeDong

[griux]

Hello,
I would like to ask you about a porcelain tea set, which my relative was given personally by Mao ZeDong, when he visited Hungary. Is is rare? Approximately how much is is worth? I would be really thankful for any kind of information.

Have a nice day.

Looks like something manufactured about mid-20th century, or a bit later.
