The password in the scratch password area on the invoice is a series of numbers specially set to prevent the invoice from being forged. You can check the authenticity of the invoice through it. The prize area is the place to tell you whether you have won the prize. After scraping it out, if it is "thank you for your patronage" or "tax payment honor" or "tax cooperation honor", then you have not won the prize. If you are told that it is "five yuan" or "XX yuan", you can cash it.
