HK-born US Permanent Resident Visiting China

Hi, I'm a US Permanent Resident (Greencard holder) who was born in Hong Kong. I hold the British Oversea National (BNO) passport, and an expired chinese "Home-Return Permit". Would BNO passport and US Greencard be sufficient to enter PRC? If not, what or travel document do I need?

I know that typically Hong Kong citizen uses the home-return permit to visit/enter, however, to renew my expired permit, I need to apply in person in HK, and since I am not able to go back to hong kong to renew the permit in person, I needed to understand what other options I have. Thanks in advance!
