Will you go to the company where you used to work?

If your previous company really needed you and you don't have a better position at present, you can consider going back.

Although "a good horse never turns back to grass", why not try to turn back when there is no better grass in front of you, or where your eyes can see it? But back to the previous unit, as you said, there is some confusion: you have to start from scratch, you have to be managed by your former colleagues, and even some old colleagues will laugh at you, and so on. Actually, none of this matters. The important thing is that you have an advantage over other newcomers, and you may be the next person to be promoted. Also, you should have the courage to prove yourself by working harder and doing better than others.

No matter where you are, do everything with your heart, and good luck is waiting for you ahead!
