Can Yizheng Sales Department enter Yangzhou Sales Department?

I can't. According to the recruitment announcement of Yangzhou institutions and Yizheng institutions before 2023, the new method of open recruitment of institutions in Jiangsu Province came into effect on March 13, 2020. According to the Announcement of Public Recruitment of Institutions (Brief), the staff of local institutions in Jiangsu Province are not allowed to apply. Therefore, Yizheng's career in Yangzhou can't be tested.
