To prepare the whole shrimp, make shallow cuts along the underside of each shrimp to help straighten its natural curve. Be careful not to cut all the way through.
To make the filling, in a large bowl, combine the minced shrimp, salt, white pepper, shiitake mushrooms, bamboo shoots, ginger, and sesame oil. Mix until evenly combined.
To assemble the potstickers, place a wrapper on a work surface. Add about 1 tablespoon of filling to the center. Place one whole shrimp on top with the tail extending slightly beyond the edge of the wrapper. Brush the edges with water, fold the wrapper in half, and press firmly to seal. Repeat with the remaining wrappers and filling.
To make the dipping sauce, in a small bowl, combine the soy sauce, Chinkiang vinegar, and chili oil. Mix well and set aside.
To pan-fry the potstickers, heat the avocado oil in a large nonstick pan over medium heat. Arrange the potstickers in a single layer and cook for about 2 minutes until the bottoms are golden brown. Flip and cook for another 2 minutes until lightly browned and cooked through.
To serve, transfer the potstickers to a serving plate and serve immediately with the dipping sauce.
