The guzheng has 21 strings.
There are many formalities used in the playing of the guzheng,
including basic plucking actions at the right portion and pressing actions at the left portion.
These techniques of playing the guzheng can create sounds that can evoke the sense of a cascading waterfall,
thunder, horses' hooves, and even the scenic countryside.
If you build your family tree and connect it to your relatives' family trees like fitting pieces of jigsaw together,
you will get a perfect big family tree which you and your relatives can share to get to know one another although they live in different cities or different countries
because the family tree explains clearly who is who.
