What you want to ask is that CUHK's postdoctoral can't be postponed? CUHK's postdoctoral fellow cannot be postponed. Because CUHK postdoctoral fellow refers to the postdoctoral fund established by Sun Yat-sen University, the postdoctoral fellow of Sun Yat-sen University no longer applies for paid extension and cannot extend it. Those who pass the examination will leave the station, and those who fail will be forced to leave the station. The fund is mainly used for supporting outstanding postdoctoral research projects, rewarding outstanding postdoctoral fellows, living allowance for postdoctoral spouses, interview travel expenses for postdoctoral fellows before entering the station, outbound evaluation fees, remuneration of co-tutors, activities fees of postdoctoral fraternity, etc.
