Could i use express service and rush servie apply hong kong visa in Korea

Dear, in regard of this question, you’d better call the embassy of PRC in Korea and ask about the detailed information. Tel:（822）756-7300
Because as far as I know, if you submit the application to the embassy of PRC and it deals with the application by itself, it usually takes 4 working days and I’m not sure if express service or rush service is provided; but if it is transferred to HK immigration department, it takes 4 to 6 weeks and there is no express service or rush service.
