Jitouguo is a common name for Euryale ferox. Bamboo knives and nets are usually used to pick the heads of chickens. People will wear waist-high waterproof pants, cut the base of Euryale ferox with a bamboo knife, and then quickly pull the fruit out of the water with a net. This picking method can effectively collect the fruit of Celosia cristata and ensure the integrity of the fruit. Picked fruits need to be cleaned and selected to ensure quality and food safety.
