As I understand from this "The Plain Bagel" video [0], they're not bankrupt. Instead, they're likely nearing the completion of their debt restructuring.
The problem is the term "bankruptcy". Colloquially people seem to think a company is just out of money. All you need to file for bankruptcy is to be unable to service debts at a specific time. It might even just be a transitory state.
A company is insolvent when liabilities exceed assets. Companies can remain insolvent indefinitely unless they miss a payment at which point a creditor can force them into bankruptcy where a court oversees liquidation.
Evergrande is insolvent and is now bankrupt. There is no reasonable scenario here where the company continues to operate as a growing concern.
