Looking at this medal, I'm reminded of my guqin (a traditional Chinese musical instrument). It was really not easy to overcome numerous difficulties and practice all the fingering techniques. I thought that playing a piece of music would be just like stacking building blocks with those fingering techniques afterwards. However, when I started playing the first piece, there was a "plucking" technique in the first sentence. I patiently continued to deal with the difficulties, but unexpectedly, an even more difficult "bumping + pinching up" technique appeared in the third sentence. Why were there so many seemingly endless difficulties? Coincidentally, I was very busy with other affairs at that time, so I pressed the pause button, and this break lasted for half a year.

The teaching assistant would occasionally shout: "Come out and practice the guqin." I thought that I should at least finish practicing one piece of music. Otherwise, it would be a waste of my money. In the fourth and fifth sentences, an even more difficult "pressing the string with the joint of the thumb" technique emerged... I practiced over and over again, but still couldn't get past the "pinching up" hurdle. The teacher gave a precise comment: "Your 'pinching up' is not confident enough. You are nervous in your heart. When it comes to 'pinching up', you have concerns, misgivings and uncertainties, so your mind is not relaxed enough, and your hands will naturally be tense. To overcome this difficulty, you just need to practice countless times."

Without countless practices, it's impossible to be confident. After practicing many more times, I seemed to have a bit of a confident feeling. Today, when I took a look, the teacher approved my progress and I reached the sixth and seventh sentences. I just took a glance and felt secretly happy. Hehe, they are just like old monsters. When you get familiar with these old monsters, they don't seem so hideous anymore.

I watched Teacher Wu Na's video again: "When playing the guqin, you should adopt a microscopic attitude, delving into each note, the blank spaces between each note, the connections between every two notes, as well as the movements of the whole body when playing each note. Every aspect is composed of countless details and tiny elements."

Making precision parts is the same as learning to play the guqin. There are constantly new "monsters" (difficulties) coming to challenge you. If you encounter several extremely difficult "monsters" one after another, it's really easy to want to give up. Do we really have to deal with these difficulties? Can't we survive without dealing with them? It's really too easy to give up on something. Fortunately, we didn't give up. In the process of constantly overcoming difficulties, our skills have been continuously upgraded, and gradually we are not as nervous or worried as before. We should be grateful to these difficulties for giving us the opportunity to grow. When you are strong enough, you will find that these difficulties are not so difficult anymore and are even a bit cute.

If we don't thoroughly understand and control every detail, it's impossible to make parts with micron-level precision.
