Can someone help me finish this little game?

Eight matches make a small fish. Move three matchsticks to change direction, analyze and solve problems (* * * takes 8 steps);

1. The picture below shows eight matches in the initial state. Two matches at the left end form a sharp fish head, two matches at the right end form a V-shaped fish tail, two matches at the top and bottom represent fish fins, and two matches in the middle cooperate with two matches at the fish head to form a fish body.

2. To change the direction of the fish, only three matches can be moved, so the idea is to make the best use of the existing matches.

3. You need to remove the "fish head" on the left of this fish first, and you need to mirror the direction of the fin on the right of this fish.

4. Use a match on the tail of the existing fish as the fish head, and bring a match from the fish head at the upper left, so that the direction of the pointed fish head will change from left to right.

5. Move the 1 match originally used as a fish fin above to the lower left to match with the original match to become a new fish tail, and the direction of the fish tail changes from right to left;

6. Finally, the 1 match originally used as the fish tail above was moved to the bottom to become a new fin, thus completing the left and right mirror image of this fish;

7. Looking back, three matches were always moved in this process, as shown below.

8. The effect after completion is shown below. Three red matches are moving, while five white matches are original.
