I heard from my friends that it is a good listed company with rapid development and a good platform for staff development. The landlord can try.
Don't worry about handing in the original. Different companies have different methods to investigate the qualifications and background of employees. Many of my friends also work in the group company, and they will all be returned to you when they leave.
Such a big company may keep your certificate to prevent you from submitting your resume again or wearing several hats.
