Don't read the next paragraph if you're not comfortable with it
About stinky tofu, there's a village-sized mega-workshop in Shenzhen, China, where 80 percent of the country's raw materials for stinky tofu are supplied daily. The place stinks all year round. A reporter disguised as a buyer to visit, I can not remember the specific details, the process is generally so, fresh tofu tofu dregs purchased, placed 3-5 days, the tofu will be wrapped in gauze square towel fermentation cesspit (animal and human feces), 3-4 days after the removal of the put into a cauldron to add carbon powder black pigments, etc., add water into the tofu to cook. Remove and air dry. This is the fragrant smelly tofu we eat on the street.
And don't ever ask why people eat it all right and I eat it and get diarrhea.
Then I will ask you why Liu Xiang can 110 meters hurdles can be the world's first, you can not.
The answer to both questions is the same.
