Does going to Shenzhen to Hong Kong and back to Shenzhen reset duration of stay?

I am a Singaporean so I have 15 days visa exemption to China. If I were to visit Shenzhen for 14 days and then go to Hong Kong and come back to Shenzhen again, will this reset my duration of stay? (i.e. I have 15 more days in Shenzhen after coming back from Hong Kong)
