Mix tofu with scallion, and buy a piece of tofu in the vegetable market. The proprietress is good at cutting, which is only a catty. Cut the tofu into small pieces and blanch it. After blanching, cool the tofu with cold water. Pour in two spoonfuls of soy sauce, one spoonful of salt, one spoonful of sugar, a little sesame oil and sprinkle with chopped green onion. Sprinkle with pepper oil and mix well.
