Hi Ninxi, your text is great, here are some suggestions to make the text flow even better ☺️
Hi, this is Ningxi. I want to introduce myself to you. I am a student who’s taking remote classes because of the pandemic. I love watching movies, TV series and reading books. I always [often?] go to the cinema [singular - otherwise you can say the movies] and musical theaters. I’ll share some of my comments on those works [on those works sounds a bit strange, you could say: on my favourite works or on some movies and plays,...?] from an amateur’s angle [point of view] in the future. Among all [the different] genres, science fiction is the best to me [I like Science Fiction best], and dystopia is even better.
