Cut the shrimp and pork into bite-sized pieces.
Thinly slice the celery.
Heat cooking oil in a pan and stir-fry the pork first.
When the pork is halfway cooked, add the shrimp and stir-fry together.
Once the pork and shrimp are cooked through, add the celery and stir-fry quickly.
Season with salt and pepper.
Transfer to a plate and serve.
