I just submitted my resume at the school job fair, saying that I would go to Guangzhou CSSC Huangpu to build a ship, but what happened to the human resources of Guangzhou Singapore Airlines?

According to what you said, Huangchuan adopted the mode of labor dispatch. This way is very common, and now many big companies such as banks and airlines will take labor dispatch. In fact, there are two understandings of your so-called normalization. One is to continue to sign a contract with the human resources of Singapore Airlines (this is still the labor dispatch relationship between you and Huangchuan), and the other is to sign a contract with Huangchuan directly (this is that you are a real employee of Huangchuan and have nothing to do with overseas companies).
