I am a Singaporean studying in China and my Residence Permit is going to expire soon, am I allowed entry to China again?

Hi I am a Singaporean studying in China. I have previously applied for a residence permit in China but it expires on 01/09. I will however only return to China on 03/09. However, I know that we have 15-days visa free for Singaporean, and the reapplication of the residence permit only takes 8 days. So will I be able to pass through custom?
