Bring chicken broth to a boil in a large pot over medium-high heat.
Add pork strips and cook for 3-4 minutes until no longer pink.
Stir in mushrooms, tofu, and bamboo shoots. Simmer for 5 minutes.
Add rice vinegar, soy sauce, chili garlic sauce, sesame oil, and white pepper. Stir well to combine.
Slowly pour in the cornstarch mixture while stirring constantly. Cook for 2-3 minutes until soup thickens.
Reduce heat to medium-low. Slowly drizzle beaten eggs into the soup while stirring gently to create egg ribbons.
Remove from heat and garnish with sliced green onions. Serve immediately.
