Passport Valid just less than 6 months (5 months 2 weeks) South African

I am a South African, I understand that I don't require a VISA for a period of less than 30 days. I have just read that my passport must be valid for a period of more than 6 months after the period of intended visit.
My passport will expire in 6 months and 1 week, but I am due to fly over to Hong Kong for an interview in 2 weeks, I will be there for about a week. Any advice please
