Is the crime of huge property with unidentified sources a presumption of guilt?

The crime of huge property of unknown origin is not a presumption of guilt. Presumption of guilt mainly refers to the presumption that the defendant is the actual criminal in the process of criminal proceedings without being convicted by judicial organs according to law. According to Article 395 of the Criminal Law 1, the crime of huge unidentified property refers to the behavior that the property or expenditure of state staff obviously exceeds their legal income, with a huge difference, but I can't explain its legal source. According to the relevant regulations of the Supreme People's Procuratorate, if the source of huge amount of property is unknown and the amount is more than 300,000 yuan, it should be put on file. Accordingly, a huge amount of property whose source is unknown refers to the property with a value of more than 300,000 yuan, which cannot explain its legal source.
