The tripe to hair points have; water fading to hair (is to put the tripe in hot water to dip a dip, and then that knife to go down the tripe on the hair. This fading method requires technology. The temperature of the water and the time to put the tripe into the hot water.) Kerosene hair removal (put a small amount of kerosene into the water, then put the tripe in. Once you see the hair fall off, it's done. (This fading method of tripe is not delicious) I suggest that tripe if you eat yourself, tripe to wash the hair (must be carefully washed, or not toothsome) do not fade, so that the tripe is more green, the flavor is also good. This is all their own experience, I am specialized in processing tripe a small workshop.
