Universities in China are for-profit organizations, and students' money had better be as black as crows. No matter where you go, you have to face these things. Everyone is as disappointed as you, but some people are ready to face them, while others are just complaining.
Don't blame me for being too blunt. I want to help you too. You're just wasting your time complaining like this, feeling sorry for yourself here, and nothing will change. You want to learn a foreign language, go out to class, learn to be a translator, and take the translation qualification exam yourself. Don't wait for the school to arrange your life and teach you the skills to make a living.
Your tuition is only used to buy a diploma, you have the conditions to enter the society, and the rest is all on your own.
Nobody lied to you. You can't miss it if you want to play. Then drop out of school and do something you think is valuable.
But after all, it is a university, and you will always see more excellent and sincere people. You will always see how others climb up, and you will always feel the atmosphere of knowledge. After all, you spent your nineteen years in a place where you should be.
You said that undergraduates discriminate against self-taught exams, and many people discriminate against undergraduates. Are all the undergraduates in China dead? It's so hot to go abroad for postgraduate study now. Don't you understand why? Because everyone is dissatisfied with the status quo and is trying to improve themselves. I am learning German by myself now, and I have just finished learning German for one year, so I can exchange majors with German teachers. I really hope that if I were you 19 years old, I could start trying to achieve something, you know?
