Unidentified Chinese food stamp [résolu]

I am having a hard time identifying one of my Chinese food stamps. 
 

1991

0.5

Google translate camera is giving me this text for the region on the first picture but I am not sure it’s accurate:

“Jiamusi City Urban Residents Tofu Series”

pics attached. 
 

Thank you in advance! I was able to easily identity my 8 other food coupons and of course this last one is the tricky one.

This item doesn't seem to be on Numista. It is considered to be forgery.

Heilongjiang (province), Jiamusi (city)

Ration ticket for half (0.5) kg of doufu (beancurd).
