In a small bowl or ramekin, whisk together the oyster sauce, sweet soy sauce, and rice cooking wine to create your stir fry sauce.
Pat the shrimp dry with paper towels to ensure a good sear.
Heat a wok or large skillet over high heat and add 1 to 2 teaspoons of vegetable oil.
Once the oil is hot and bubbly, add the shrimp. Stir fry for 2 to 4 minutes until the shrimp are pink and opaque. Remove the shrimp from the wok immediately and set aside.
Add another 1 to 2 teaspoons of oil to the wok. Add the garlic and ginger and stir for just a few seconds until fragrant.
Toss in the snow peas and stir fry for about 1 minute until they turn a vibrant, darker green.
Return the cooked shrimp to the wok and pour in the prepared stir fry sauce.
Stir everything together for about 1 minute until the sauce is bubbly and coats all the ingredients perfectly.
Remove from the heat promptly to prevent overcooking the shrimp and serve immediately over rice.
