No way round it. You only other option is to remain illegally in China and hope that you're never caught by the authorities.

Keep in mind that the longer you stay, the more likely you will go to jail and then deported. Without ever returning to China in future.

Depending on your Nationality, it mightn't matter a day or 2 expired. Some passports simply aren't favoured by China.

I had guanxi, 30 days expired... lets just say the connection I had working on my behalf there is none higher in the particular province. I still had to pay the fine to leave!

Bite the bullet, go without eating and pay. It's your only option.
