　　Explore the ancient nine-square grid password and start a journey of wisdom

　　In ancient times, the nine-square grid (also known as "Luo Shu" or "Luo Shu Jiugong") was not only a treasure of mathematics, but also an important tool for enlightening wisdom and training thinking. Mastering and familiarizing yourself with the nine-square grid password will not only bring a lot of fun to your math and brain teasers, but also bring out its unique benefits in everyday life. So, how to better memorize and apply the nine-square grid mantra?

The key to memorizing the mantra：

　　First of all, we need to understand the essence of the ancient nine-square grid mantra: "Two four is the shoulder, six eight is the foot, the upper nine is the lower, the left seven is the right three". This mantra is not only a shortcut to arithmetic, but also an excellent metaphor for space and orientation. When you face the nine-square grid, you can think of it as an independent kingdom, where "up" and "down" refer to the top and bottom, while "left" and "right" correspond to the leftmost and rightmost sides. Remember that the core of the center should be five, because it is in the center.

Tips for answering：

　　When you need to fill a space, first observe the number that has been filled. For example, if you see a 3 already connected to a line prime on a line, then the next space in that line should be filled with 9 (because the top and bottom complement each other). In the same way, if you check all the occupied numbers row by row, you can quickly draw conclusions. It's not just a speed game, it's a journey of mental exercise.

Further expansion：

　　You can try playing a few rounds of nine-square grid games during your daily breaks, or challenge your friends around you to a "duel". In addition, if you have the conditions, you can also participate in the "Nine-Square Grid Competition" held on some online platforms to master skills and improve your wisdom in actual combat. When you encounter a bottleneck, you can ask your math teacher or seek answers and guidance on the Internet.

　　In short, exploring the ancient nine-square grid password is not only a mathematical competition, but also a feast of wisdom for the soul.
