Soak the dried shrimp for 10 minutes. Set aside.
Next make the broth! Add pork to a large soup pot and cover with water until it just covers the pork. Bring to a boil and boil for 2-3 minutes. Remove from the heat.
Place the pork on a plate and pour out the water. Rinse the pot and add the pork back to the pot. Cover with fresh water until it just covers the pork. Add the onions, dried shrimp, and daikon. Bring to a boil and simmer for 2 hours.
While the broth is cooking, cook your tapioca noodles and prepare your toppings. Mince the cilantro and green onions. Boil your eggs. Set it all aside.
After 2 hours, add the chicken broth, salt and sugar. Taste the broth for seasoning and add more salt if it tastes bland.
The broth should be done at this point. The last step is to cook your seafood toppings - shrimp, squid, octopus, fish balls, and imitation crab. Bring the broth to a boil. Using a ladle or any large spoon, scoop spoonfuls of each topping and hold them under the boiling broth until they are cooked through. Once cooked, set them aside in a bowl. Repeat this process until all your seafood is cooked. The reason we don’t leave the toppings in the broth is because we don’t want them to overcook.
Now you can prepare your noodle bowls! Add some of the tapioca noodles to a bowl. Top with the cooked seafood, bean sprouts, chives, cilantro, green onions, boiled eggs, and fried shallots.
