What exactly does "brothers fighting tigers, father and son go into battle" mean? What intention does it express?

Only for armored men, let me tell you about your feelings. I originally bought this one because it can be replaced and has different feel. I am 122cm, and I can use my thumb, ring finger and little finger to pinch the mouse. My hand length is 182mm~ 185mm (distance from the line closest to the palm when the palm is straightened and the wrist is slightly bent inward to the top of the middle finger) The thickest part of the palm is 48mm (near the base of the thumb and close to the wrist) The length of the index finger is 72mm (the end of the finger) After reaching the base of the finger), I first changed both sides to a larger side. I first found that after changing the right side to a larger side, the bulging part was too long and there was no place to put my little finger (the little finger only pinched the largest back part), which was very awkward. Then change the right side back to the small side. At this time, the large side on the left side obviously hinders the thumb from pressing the two side buttons (at this time, the side button protrusion is almost flush with the big side). Finally, they all changed back to the small sides. It's finally acceptable. Then I played FPS games for about 3 hours, and I found that the biggest problem is the layout of the side buttons on the left. When I use it in a pinch-mouse style, I can’t accurately press the left button without letting go and moving my thumb forward. Front side keys. It turns out that for me, the most suitable pinching method is to pinch the mouse diagonally (using my thumb under the left front button). In this way, it can barely be used, but the impact on FPS games will be too great. I also found a problem, that is, when the mouse is placed on the desktop above the level where the elbow is placed, the problem of not being able to press the side buttons is not obvious, but when the mouse is placed on the computer table below the level where the elbow is placed, When the drawer is flat, the rear button is often pressed when pressing the front button. I talked about a lot of shortcomings when using it, and finally talked about what I think are the advantages. The two side buttons are crisper to press and the rebound is faster than the side buttons of the G9X. Furthermore, the lighting effect is good. It still has a breathing light effect without installing the driver. Compared with the lighting effect of the Wrangler, which has been explained and advertised on the Internet, it is much more restrained. Of course, it doesn't matter to me whether the mouse has a light or not. , and when watching online movies, the breathing light effect is more eye-catching than the keyboard light.
