Secondly, you need to determine who owns the money, the school or the teacher, which also needs relevant evidence!

Then analyze according to the existing situation!

In the worst case, there is this money, but the supplementary unit will be allocated to the school (indirectly, it can be regarded as a reward school), and then the school will reward you (in kind or part of the money)! In this case, you can't get your money back There is nothing wrong with teachers and schools!

In the best case, the beneficiary of the grant is your name directly, and the school gives it all to the teacher, and you only get a small part (goods or money), so the teacher privately occupies a part of the arrears! This can be taken back, and the school will definitely investigate the responsibility, but it needs evidence to prove it!

The other is that the beneficiary of the grant is your name directly, but the school deducted some money and you only got a part! You can't fight the school! Even if you have evidence, the school's charging system is independent! You can swallow it in another direction and start talking! And if you get into trouble with the school, you may not get along well in the new school in the future (many schools have relations, and society also has relations)! I suggest you give up!
