ATC is there for a reason John (and it isn't just to keep you company while your aircraft follows a pre-programmed route from A to B). If you were to ignore them in real life then you would very quickly find yourself being escorted by a couple of military jets to the nearest available airfield where you would have an awful lot of explaining to do to the authorities before losing your Pilots Licence.
Thankfully you are only flying a sim and, since the current crop of ATC plugins are buggy at best (and the built-in X-Plane ATC is downright lethal), I suppose that you could be forgiven for ignoring some of the more weird instructions that 124th may have given to you. That said; flying a sim aircraft like the Zibo 737 involves a whole lot more than just selecting the autopilot after takeoff and doing an ILS autoland at the other end!
Perhaps it's time for you to study up on how to actually 'hand fly' a 737 so that the next time that ATC asks you to do something that means deviating from your programmed course and altitude then you will at least have the knowledge and satisfaction of being able to comply with their requests?
Have a look at this guys' channel. A real-life 737 pilot who is also a tester for the Zibo mod in his spare time. It might be a good place for you to start...
