The specific steps for painting fish in traditional Chinese painting are:

1. Hold the pen with the palm of your hand facing down, put down the paper with your palm facing down, move the pen to the upper right, and slowly move the pen edge during the stroke. Lift up, switch the horizontal-front pen to the center-forward pen as you gradually lift the pen, making the strokes gradually taper and drag out the tail handle. Then outline half of the tail fin. Then add another stroke to outline the other half of the tail fin.

2. Use the center to outline the head of the fish, point out the two eyes, and draw the pelvic and anal fins.

3. Use an outline pen and light ink to outline the fish scales. Starting from the bottom of the fish's head to the tail handle of the fish, draw a dozen lines at equal distances from the upper right to the lower left, and then draw them again in a cross pattern. When the ink is half dry, use burnt ink to outline the dorsal fin on the back of the fish.

4. Hold the pen with the palm of your hand facing down, the tip of the pen lying on the paper toward the upper left side, and the pen stroke in an arc toward the lower right side. In the process of moving the pen, rotate the pen barrel to the lower right, gradually convert the horizontal pen to the center pen, drag out the tail handle and then close the pen, and then use the center pen to draw the tail fin in two strokes.

5. Finally, hold the pen lightly, palm down, and gently draw the fish's whiskers with the tip of the pen.
