Hakka-Style Squid and Pork Belly Stir-Fry

Heat oil in a large skillet over medium heat. Add pork belly and fry until oil is released, 5 to 7 minutes. Add bean curd and fry until it turns yellow, 3 to 5 minutes. Add squid, bell pepper, and garlic; fry another 3 to 5 minutes.

Add water, soy sauce, and cooking wine to the skillet with the pork belly mixture. Add sugar and white pepper; fry for 3 minutes. Add celery and garlic sprouts; fry until fragrant, about 3 minutes more.
