Nagaimo (Mountain Yam) Chicken Soup - 淮山鸡汤 Recipe

• 2-3 chicken carcasses (bones), parboiled; 1 Nagaimo (picture above), peeled and cut into circular chunks; 1 medium-size carrot, peeled and cut into circular chunks; 2-cm knob ginger, slightly crushed; salt to taste; half a pack of willow mushrooms is optional here (Note: use of willow or bunashimeigji-type of mushrooms preferred since fresh shitake has a much stronger taste and may overpower the soup which I really want to taste the yams)
