The times are progressing and technology is developing. Some food stamping processes should be cancelled. From the health point of view, it will never be safe, and it is also an uncivilized process.
Now that AI technology is so developed, let's take writing with a brush as an example. Japanese AI robots imitate all the details of calligraphy masters, including wrist strength, brush inclination, stroke order, line thickness and pen pressure. Not weaker than the master of calligraphy.
This kind of robot can also be used in various trampling processes. Combining rigidity with softness, the effect is greatly improved. The traditional craft was a last resort in the backward times, and now it is still using the stamping craft, which is decadent and can't keep up with the times.
