adapted from The Woks of Life "Sichuan Dry Fried Green Beans"
Heat wok over high heat until it begins to smoke. Add the green beans and salt, lower heat to medium-low and sear, stirring occasionally until tender and blackened in spots, about 20 minutes. Transfer the beans to a plate.
Combine soy sauce, Shaoxing wine, sesame oil, and sugar in a small bowl and set aside.
Heat the oil in the wok and add the pork. Stir it around to break it up and brown it, a couple minutes. Add garlic, chiles or chile-garlic paste and stir fry for a minute. Add back the green beans, drizzle in the sauce, and increase the heat back to high. Stir fry for a minute and serve.
