Along the thighs, wings, and breast joints, use a knife to dismantle the chicken into smaller pieces
Place all the pieces, except for the breast, into the pot. Add water to the pot until the water surface is about 1-2 inches above the chicken parts
Place the pot on the stove, and turn the heat to high. Bring the pot to boil for about 2 mins. Remove the scum with a spoon
Put the breasts into the pot, and make sure they are submerged under the water
Once the pot is back to boil, turn heat to low, cover it with a lid, and simmer at low heat
Add ice and cold water to the sauce pan after 18-19 mins
After the pot simmers for 20 mins, take the breast out, and put them to the ice water to quickly cool down. Keep the chilled breast for another dish
Put the lid back on and simmer for another 50-55 mins. Remove the pot from the heat and cool it down
Take the chicken pieces out of the stock, and remove all the meat from the bones. Put the bones back into the pot, and add additional water (3-4 cups). Put the pot back onto the stove and bring it to boil. Turn heat to low to simmer for about 30 more mins with the lid on
Remove the pot from the heat, and cool it down to room temperature. Place it in a refrigerator overnight. Use a spoon to scoop out excess grease on the top. Warm up the stock for the next step
Peel, rinse, and mince the onion and carrot
Place the sauce pan onto the stove. Add oil and the minced veggies. Turn heat to high and sautee for about 2-3 mins. Add 5-6 cups of the stock.
Bring the pan to boil. Add the egg noodles, mixed herbs, and stir to mix
Turn heat to low, and let the pan simmer with lid on for about 15-50 mins until the noodles are soft
Add the chicken meat, white pepper powder, and salt. Turn heat to high and bring it to boil for 2-3 mins with stirring
Adjust with salt to your likings
Serve as it is or a side dish
