I am really confused for lost passport in China

I lost my US passport along with my China entry permit in it.. I am currently in China.I need to exit China in two days. I made my emergency passport from US embassy in Guangzhou.I went ask at the local public security bureau and they said I will need to wait 7 working days to get my replacement China entry permit. Without it, I can't sit China. What should I do?Is free transit can let me exit out from china without my china entry permit? Very Urgent!!
