It is actually very simple to make four lines and three grids in Word to facilitate pinyin practice. First, open Word, create a new document, click the Insert tab, select the Table function, and insert a single-row and single-column cell.

Next, fill in the inserted form with the pinyin you need to practice, and make sure that the font is clear and easy to read. This step provides a basic framework for your pinyin practice.

Then, go to the Insert tab, switch to the Shape function, and select the Line tool. Draw two horizontal lines in the table and adjust their positions, so that the table forms four lines, and the upper two lines and the lower two lines are evenly spaced, forming a three-grid layout.

Finally, make sure that your three squares are the same size, so that your four lines and three squares are completed. Now, you can start your pinyin practice in this custom grid, without looking for a template, just operate it directly.
