Grate garlic and ginger; mince leek, cabbage, spring onions, and chives.
Add soy sauce, Shaoxing wine, oyster sauce, sesame oil, white pepper, salt, sugar, and MSG. Mix well.
Throw the mixture into the bowl several times to develop texture.
Place 1 tsp filling on each wonton wrapper. Wet edges, fold into a triangle, then seal the two corners together.
Heat oil and fry sliced shallot until golden; remove. Repeat with garlic, then peanuts. Set all crunchy bits aside.
Add ginger, garlic, star anise, cinnamon, coriander seeds, and bay leaves to the oil. Infuse 15 minutes, then strain.
Combine gochugaru, Sichuan pepper powder, chili flakes, sugar, salt, MSG, and black vinegar in a heatproof bowl. Carefully pour hot oil over and stir. Mix in the fried shallot, garlic, and peanuts.
Bring a pot of water to a simmer. Cook wontons 4-5 minutes until they float.
