Hi, I am malaysia citizen and used to have a working Z type in china

& due to some changes, company has cancelled my working Z type in china, and currently my company requested me to fly back to China for handover, as such, I am advice to apply for single-entry business M type, and requested to fly out before the expiration date, but I wish to revisit china after the exit, so I am thinking to apply the China Visa in Hong Kong, instead of flying back to malaysia. Is that possible for a malaysian to apply a china visa in HK?
Kindly advice.
