First of all, it is illegal for the hotel to force you to train for two hours, which does not count as work and does not guarantee the normal rest rights of employees;

Secondly, it is illegal to sign a contract and deduct wages without signing it. Article 9 stipulates that an employer shall not detain the employee's resident identity card and other documents, and shall not require the employee to provide a guarantee or collect property from him in other names.

(1) Causing the other party to conclude or change a labor contract against its true meaning by means of fraud, coercion or taking advantage of the danger of others;

In a word, the hotel has done many illegal things. You can apply for labor arbitration and claim compensation from the hotel. The specific way is to apply to the labor arbitration department, and they will tell you what to do, and it is free.
