To make the tofu cream, place the tofu, tahini, sesame oil, garlic, salt, white pepper, and water into a food processor. Blend until smooth and creamy, and set aside.
In a small bowl, combine the soy sauce, sesame oil, Shaoxing cooking wine, sugar, cornstarch, and water. Mix well.
Place a large skillet over medium heat and add the vegetable oil.
Add the garlic, ginger, chili, and bok choy to the skillet and fry for 2 minutes or until the bok choy begins to wilt.
Cover the skillet with the lid and allow the bok choy to steam for 2 minutes.
Remove the lid, pour in the soy sauce mixture, and toss to coat the bok choy. Remove the pan from heat and set aside.
Dollop the tofu cream onto a large serving plate and smooth the top with a spoon.
Top the tofu cream with the cooked bok choy and remaining soy sauce mixture.
