Technology evolves rapidly, and we need to maintain keen learning abilities and curiosity. Every mastery of new technology is an investment in the future. Here we record thoughts and summaries in the learning process, sharing methods and experiences for solving problems. Through continuous practice and summarization, we transform knowledge into real skills. Only practice‑validated methods and technologies truly help solve real problems. You can find algorithm solutions, technical notes, and project practices here.

尺规作图（Compass-and-straightedge Construction）是起源于古希腊的数学课题。只使用圆规和直尺，并且只准许使用有限次，来解决不同的平面几何作图题。
