1. Contact the school: contact the Admissions Office of Liaoning University of Petrochemical Technology or relevant departments to find out the specific reasons and policies for the restrictions. More information will be provided and further actions will be guided.
2. Consider other majors: I have a strong interest in Liaoning University of Petrochemical Technology, but I was admitted to a restricted major. You can consider applying for other related majors. This will increase the chances of being admitted, and at the same time, you can receive relevant training and study in related fields.
