I think height is not very important. First of all, not to mention how beautiful your face is, at least it should look pleasing to the eye and generous. Your body should not be too fat (the audience will think you are fat like this) and you must love hosting. Love to eat. . You should be good at explaining how it tastes and how it tastes and how it feels. As for the host, the university is Communication University. I have never seen a host who has not gone to university. Come on.
