I am a fresh undergraduate, and I am looking for a job. Who can tell me the monthly salary of hardware engineers in Tianjin Tiandi Ye Wei Company? !

A few days ago, I got the offer of embedded software engineer of this company when I was recruiting on campus, but I didn't agree to let it go after discussing with my family. At that time, the offer said that the probation period was six months, the official salary was 4200, and the Tianjin hukou was settled, providing lunch subsidies. There is no welfare during the probation period, and the salary is 3400. One thing to note is that as a software engineer, he always says that he will go on a business trip to the mine to debug programs and hardware, which seems to be more frequent.
