Rub salt all over the pork. Let it stand for 1 to 2 hours.
Steam the salted pork for 30 to 40 minutes.
Let the pork cool down and then shred the pork using your fingers. Set Aside.
Prepare the congee by combining 4 to 5 cups of water with the chicken stock in a large cooking pot. Boil.
Add the rice and then wait for the liquid to re-boil. Stir every 5 minutes. Continue cooking in medium heat until porridge-like texture is achieved (usually about 30 minutes or more).
Transfer the congee in an individual serving bowl. Top with sliced century egg, shredded salted pork, and scallions.
