clean the beans, and remove head and tail defects.

with water, boil the water in a large pot, put in the fresh beans, turn them over with chopsticks so
that the beans are evenly heated, bring to a boil over high heat, and scoop them up immediately .
3. Cooling: After boiling, put the beans taken out into cold water to cool, and then remove the dry
water. After scooping out the blanched beans, immediately put them in cold water to cool down,
then scoop them out of the dry water.
