Eternal Calendar in Chinese

Design the months and days of the week in Chinese characters, making it easy for both children and adults to understand and play with!

The assembly instructions have arrived!!!

1. First, arrange the days of the week and months neatly according to the image above.
    

   

2. According to the image above, insert the months into their respective boxes. Note that there's a slight error in the image: the boxes with a through-hole in the middle should contain the days of the week, while those without the through-hole should contain the months.
    

   

3. Due to the large number of date cards, I will not list them one by one. Following the order of the months, they are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, nextmonth, and a smiley face. When inserting them, ensure they face the right side, distinguishing them from the months.
    

   

4. The assembly process is relatively simple, and the final assembly result is shown in the picture. It's important to note that the middle hole requires a steel pin with a length between 55-58mm or you can use filament. The two larger holes on the sides are covered by the lids for the months and dates, while the smaller hole in the middle is covered by the lid for the days of the week.
5. Insert the steel pin first, align the three boxes, then insert the two brackets, combining the semicircular sections into a complete circle. After inserting one side into the hole, place the three boxes horizontally. Finally, gently pry open the bracket on the other side and insert it into the opposite hole to complete the installation.
