Douchi, fermented bean curd, stinky tofu and mature vinegar, how are these foods processed and manufactured? Is it harmful to your health?

Douchi, fermented bean curd and stinky tofu are all fermented bean curd processed foods, and modern technology is mature, so you can safely eat them! Of course, in order to maintain it for a long time, a lot of salt will be added, and long-term consumption in large quantities will increase the risk of hypertension.
