Why is Hermione hated by Snape, Trelawney and Umbridge in Harry Potter?

I think hermione granger knows too much. In the book, she appears as a girl who likes to delve into learning and knows everything. Sometimes she seems to be arbitrary. Her knowledge proved useful in many of their adventures. The only major she doesn't like is divination, which is considered as "inaccurate" knowledge.

When Hermione arrived at Hogwarts, she quickly became the cleverest student in the whole grade. She not only knows the answer to every question, but also remembers the contents of every book she has read, and is willing to tell others her knowledge. Therefore, she won the nickname "Gryffindor know-it-all" shortly after her school career began, and she was famous for raising her hand actively to answer questions in every class and never taking pains. As Harry Potter's best friend, he helped Harry build Dumbledore's army and secretly studied defense against the dark arts.

At the end of the film, Umbridge is successfully lured into the dark magic forest, thus getting rid of Umbridge's entanglement. After Wood left, Ron became a goalkeeper. When someone looked at him, he always behaved badly. Hermione also had contact with Cramer, which made Ron always jealous. Although everyone in the school believes in daily prophet, Zhang Qiu is very enthusiastic about him. Umbridge became a senior investigator. She checked every honest class and then reported to the Ministry of Magic. Everyone hates this snob. Hermione started a movement because she didn't teach her students any spells at all.

First of all, the early professors didn't have much enthusiasm for Harry, and they were fair to all college students. It is inappropriate for a teacher like Snape to take sides unconditionally. Most teachers obviously prefer to learn to bully Hermione. For example, Professor McGonagall, the president of Lion College, has always treated all students equally. Harry took someone on a night trip, and she immediately deducted 150 yuan from her school. Praise Hermione in Flitwick's class every day. If she doesn't behave well, Harry will criticize him and give him more homework.
