Is there fraud in part-time recruitment of Qidong Sky City?

It is normal to eat one to gain wisdom. There are many situations like you now. Therefore, any company, whether part-time or full-time, can only be guaranteed if it is written in black and white and signed by the person in charge! Even if the promise is not fulfilled, you can go to labor arbitration. No evidence is useless! What you say is empty, hehe!
