To prepare the chicken, in a bowl, whisk together the salt, ginger puree, and Shaoxing wine. Rub the mixture all over the chicken, inside and outside, then marinate for 20 minutes.
To make the chili garlic sauce, in a bowl, combine the sesame seeds, garlic, scallions, and red chili flakes. In a small pan over high heat, heat the cooking oil until smoking hot, then carefully pour it over the garlic mixture. Stir in the Chinkiang vinegar and soy sauce.
To steam the chicken, brush the chicken lightly with cooking oil and place it breast-side down on a plate over a steamer rack. In a large pot over high heat, bring water to a boil. Reduce the heat to medium, transfer the chicken to the pot, and cover. Steam for about 40 minutes until fully cooked through and the internal temperature reaches 165°F (74°C).
To serve, shred the chicken into smaller pieces with your hands or chop with a knife, then serve with the chili garlic sauce.
