No water is needed. the small bowl I'm place few pieces of Pao Sheng (泡参) inside then cover w small bowl n arrange the chicken in. For pic 5 is done pic after 3 hr of boil which u can't see the essence soup as it hide inside the small bowl. U have to remove the bowl then the soup will come out.
(Please note the chicken skin have to remove to prevent the soup too oily)
