Cut pork tenderloin and tofu into 1/4-inch strips. Set aside.
Slice wood ear mushrooms, shiitake mushrooms, and bamboo shoots. Set aside. If you use dried shiitake mushrooms and wood ear mushrooms, you need to soak them in water beforehand so they can absorb the water. This will take about 2~3 hours. Bring the broth to a boil.
Add the pork, carrots, wood ear mushrooms, and shiitake mushrooms cook for 5 minutes.
Add tofu and bamboo shoots to cook for another 1 minute.
Add cornstarch and stir for 1 minute.
Add soy sauce, salt, white vinegar, white pepper, and sugar, and season to taste. At the same time, stir with a spoon to distribute the seasoning evenly.
Then slowly pour the beaten eggs into the soup while you keep stirring to make long egg ribbons.
Ready to serve, sprinkled with green onions and sesame oil.
