Why did Mu Yuan resign twice, but the third time was not worthy of the name?

I resigned twice and couldn't get in. Muyuan employees left the company twice normally, and they could not sign the company in the month of leaving, so they needed to re-enter the company in the next month. So Mu Yuan couldn't get in because he resigned twice. Mu Yuan Group, located in Nanyang City, Henan Province, was established in 1992. After 30 years of development, it has now formed a comprehensive modern enterprise group with pig breeding as the core and integrating feed processing, breeding pig breeding, pig breeding and slaughter processing.
