If the playing method is incorrect, the knuckles will be insensitive, the arm muscles will be sore after playing for a while, and the tone will be unreal. To grasp the accurate timbre of the guzheng, we must use the scientific method of playing the strings.

1. The shoulders and arms are relaxed and sag naturally. Generally, the force used to loosen the arm is equal to the gravity it receives, and it should not be higher than this gravity (unless it is necessary to develop the force of the upper and lower arms to play the music). The correct feeling is the feeling that the arm is about to fall without falling. The arm only acts as a steering wheel, and the force when playing the strings is coordinated and concentrated on the fingertips or palms. The resulting sound is bright and solid.
2. Choose the appropriate string speed to practice. Usually when you play the strings with explosive force, the sound is crisp, transparent and clean, but if a beginner uses this method, the arm muscles will be tense, and they will become sore after practicing for a while, which is commonly referred to as "playing the piano with your shoulders on." At this time, you can change from fast to medium speed for playing training, and play again at a one-second interval after each sound. The muscles will naturally relax. The tone is also relaxed and pleasant.
3. Choose the right string strength to practice. Like many people crowding the bus like a swarm, everyone is very tired, and the process of getting on the bus is much more comfortable if there is a queue. The strumming force control should also be so unhurried, the force is not always better, the force "plugged" hard on the string will produce a harsh or too tight sound. The usual force is to put aside artificially heavy or too light force, that is, not deliberately heavy or deliberately light. Play the strings like this. It will produce a round, full sound.
4. Choose the "light" strumming method. If you strum the strings slowly and lightly, as if you were touching the strings, rather than strumming the strings, you'll have a weak, dull tone. If it is fast and powerful. To make the muscles tense, you can take the "light" strumming method with the shrapnel off the string. That is, the speed of strumming is fast and the force is light. Although the sound produced by this method is weak, there is still a bright sound. No matter how thin a person is, they still have bones. After a period of practice in this way, the muscles will relax and the tone will be firm and bright.
5. Use the palm of your hand to play the strings. Especially when playing a big shot. If you look for a "grip" feel, like a baby holding an adult's hand, the tone will be thick and bright. This method is also known as "grabbing the zither" in the traditional sense.
