php editor Yuzi will reveal with you the strategy for unlocking all the skills of Winter Rhapsody. This character plot simulation game is based on a small town story and incorporates Japanese elements. Skills in the challenges are crucial, and the game is packed with fun content. By unlocking all skills, you will have a richer gaming experience!

1. Open the geometric sketchpad, select [Custom Tools] - [Quadrilateral] - [Rhombus (including diagonal)], draw a rhombus ABCD, with the axes of symmetry as AC and BD.

Construct a perpendicular line on the edge of AB, the vertical foot is P, and DP intersects AC at point O. Mark AC as a mirror surface, and make a symmetry point P' about point P about AC. Similarly, mark BD as a mirror surface, and make a symmetry point P'' about point P about BD.

3. Select points O, P, and P’ in sequence and execute the [Construct]-[Arc on Circle] command to construct the arc PP’ on the circle. Then use BD as the mark mirror to construct a symmetrical arc.

4. Select points D, P’’, and P in sequence, and execute the [Construct]-[Arc on Circle] command to construct the arc P’’P on the circle. Then use AC as the mark mirror to construct a symmetrical arc.

5. Hide redundant objects, and finally the four arcs form an ellipse.
