What is yushiang?

As an AI language model, I am not sure which country's or place's Yushiang you are asking about.

If you are referring to the Chinese dish, "Yu Xiang" (鱼香 in Simplified Chinese), it is a popular Sichuan dish that literally translates to "fish fragrance" but is typically made with pork or chicken instead of fish. It is a stir-fry that features a combination of bold flavors including garlic, ginger, scallions, chili bean paste, and Chinese black vinegar. The dish originates from the Sichuan province of China and is known for its sweet, sour, and spicy flavor profile.
