Bamboo flute joke

In fact, there is no difference. There is no relevant national standard for this thing. The so-called high-quality, super-quality, advanced, ordinary ... are some tricks used by merchants to fool people. Find a seller whose eyes haven't completely turned red (remember Huang Hong's joke at the Spring Festival Evening, which is a bit far-fetched) and explain your specific requirements to him. It mainly means that if you are not satisfied, you can return it, which is ok. Take your time!

I wish you a good flute set. Have fun!

What is said upstairs is also reasonable, that is, I think it is better not to connect the flute with copper. As for why, people have different opinions.
