Could you start by slicing the chicken into thin slices? You can freeze it for 30 minutes to make it easier to slice. Then, add sliced chicken to a large bowl. Next, add baking soda, cornstarch, rice wine vinegar, and cold water. Mix well and set aside.

In a large wok, add 1 tbsp of sesame oil, and sear the chicken on medium high heat, mixing occasionally, until it is golden brown. Remove and set aside.

In the same wok where you cooked the chicken, add 1 tablespoon of sesame oil and cook the garlic until fragrant. Then, add soy sauce, chicken broth, hoisin, Shaoxing wine, and sugar. Mix everything together. In a separate bowl, combine 2 tablespoons of cornstarch with 2 tablespoons of cold water to make a cornstarch slurry. Slowly add the slurry to the sauce, mix well, and simmer for 2-3 minutes.

Add in cooked chicken, steamed broccoli, and mix. Serve with favorite sauce! Enjoy hot.
