Why is Nana so annoying?

Nana, as the front-line host of Hunan Satellite TV, also has charming sunshine temperament. Because this kind of informal personality, although it seems very casual to everyone, people will not care about him, but after a long time, it reflects a host's personal accomplishment and style, which makes everyone feel that she has some achievements, and more is that she can do it. Sometimes she just says it regardless of the occasion, regardless of other people's feelings and does whatever she wants. This is absolutely impossible, because it represents not a TV station it represents, but a status symbol. So, slowly, because he is always strong and informal, this character sometimes hurts others' self-esteem and makes others unacceptable, so now his popularity is slowly declining, and many people hate the idea similar to mine. Just adopt it.
