Bench for bench making

The traditional Chinese small bench, it is beautiful and durable. The production of the bench has a certain technical content. The angle of the bench is one inch put two minutes (actually the length of the horizontal square is also one inch put two minutes. This is the experience summarized by the traditional Chinese craftsmen, and we should not forget that our ancestors have left us a lot of valuable wealth). Now are changed to use the metric system instead of the city system. So by actual measurement, the angle of the bench is 12 degrees. I guess not all benches are 12 degrees! For example, bar stools and other stools of different lengths, it is normal to change the angle a little for aesthetic and practical reasons. The practical angles are 10, 12 and 15.
