Cut the white radish into equal, round slices. Finely chop the scallions.
Use the face of your knife to smash the shrimp.
Combine the shrimp and ground pork in a bowl together with soy sauce, sesame oil, tapioca flour, minced garlic, sugar, salt, pepper, and chopped scallions.
Mix well to infuse the filling with all the spices and seasonings. Wrap the filling bowl with food wrap and refrigerate it for about 30 minutes.
Pour the chicken broth and white radish into a pot. Cook it over medium heat for about 20 minutes.Afterward, season the broth with salt and sugar. Scoop a spoonful of filling onto a wonton wrapper.Fold it by bringing the edges together, then gently seal the wrap (see the included photo and video for a clearer demonstration).Repeat the above steps for the rest of the wrappers. If you have some leftover filling, you can shape it into small meatballs and cook them together with the wontons.
Bring a pot of water to a boil over high heat. When the water has come to a full boil, add the noodles and stir them with chopsticks to prevent them from sticking together.After 3 minutes, drain them using a sieve, then transfer them to an ice bath. Drain the noodles once more and put them in a bowl. Bring another pot of water to a boil. Blanch the bok choy for about 4 minutes, then put them into an ice bath.
Pour water into a pot, then immediately add the wontons.

Place the noodles in serving bowls and put the wontons and bok choy over them. Sprinkle fried garlic, scallions, and pepper on top.Pour the broth into the bowls and enjoy.
