There is a fierce debate in China now, whether a patient or his relatives should pay extra money stealthly to the doctor in charge for better cure?

since many incidents happened to patients due to carelessness or something in public media. many new patients and his relatives would rather to pay such money to the doctor.
This phenomineon is very popular in China, to some doctors, income of this kind is far higher than their payment.

Now the debate is hottest topic in China.

If you can tell me whether happens in you country, how the law deal with it?

Thank you in advance.
