Rinse the shrimp and pat them dry with paper towels. Trim off the long antennae and the sharp end on top of the head.
Soak the glass noodles in warm water for 10 minutes, or until soft. Drain and set aside.
Cut the cabbage into slices. Arrange the cabbage in a single layer in a cooking clay pot (or cast iron pot). Add glass noodles on the second layer and top with shrimp. Set aside.
Meanwhile, prepare the sauce. In a small bowl, combine garlic, half of the chopped green onion, and ground white pepper. Heat the oil over medium-high heat until it begins to smoke, then pour it over the garlic and green onion to sizzle. Next, add soy sauce, fish sauce, oyster sauce, sugar, and rice wine, and stir well.
Pour the sauce evenly over the shrimp in the pot, cover, and cook for 10 minutes over medium heat. Turn off the heat and let the pot sit covered for another 5 minutes; the residual heat will continue cooking the noodles. Give the noodles a gentle stir before serving.
Sprinkle the remaining green onion on top and drizzle with sesame oil. Serve immediately.
