Men use their practice to nourish the essence and inject yang energy into exorcising demons and yin. Women can use their bodies to absorb male yin energy, temporarily put it in their bodies, and inject the yang energy in the body into the recipients to protect their primordial spirit. Since the yin energy absorbed is not produced by itself, it will harm the body in the long run. Therefore, they need to return to the altar regularly to receive yang energy infusion, remove the yin energy and store new yang energy. Simply put, male and female disciples have their own functions, and they are indispensable.
