Place the tofu into a large bowl, and mash it into a paste with a large spoon. Stir in the pork, cornstarch, egg, 1 teaspoon chicken bouillon granules, and 1 teaspoon salt until the mixture is very well combined.
Heat the water and vegetable oil to a boil in a large saucepan, and reduce heat to an active simmer but not a full boil. Using gloved hands, pinch off about 1 tablespoon of the tofu mixture, roll it into a ball between your palms, and slide it carefully into the water so it doesn't break apart. Repeat with the rest of the tofu mixture. Without stirring the soup, let the tofu balls simmer until they rise to the top, about 30 minutes.
Turn off the heat, and stir in the dried shrimp, pea vine shoots, 1 teaspoon of chicken bouillon granules, and 1/4 teaspoon salt. Serve hot.
