Is it good for boys to learn guzheng and flute? It will improve their own temperament, right?

What you said is good, guzheng and flute can improve their temperament.

The guzheng was originally played by men, before '85, most of the guzheng teachers in the country were men, and most of the ancient masters of the guzheng were men, Zhou Yu and Cao Zhi were masters of the guzheng, and Bai Juyi and Su Shi also studied the guzheng, and the best of the modern guzheng players, Wang Zhongshan, and the young guzheng players, such as Liu Le and Ren Zhuoyang, were all men, and those who say that the guzheng is feminized have ulterior motives.

Piano and violin in China now are also the majority of girls learning, why no one said that the pianist female musical instruments?

The flute is also a great instrument, portable and easy to start.

Finally, I would like to share with you a common sense: musical instruments are neutral, there is no gender identification, men can use it to express men's thoughts, women can also be used to express women's feelings, the instrument itself has no gender. Just like the pen, men write twisted words do not blame the pen feminized, the word such as their key to see how to use, musical instruments are also, the key to see who use, how to use.
